[0003] If an extreme value algorithm is used to allocate tolerance, it is easy to have a situation that the gap tolerance is too large to break the overall requirement or the individual composed ring requirement is too strict to be realized. If a statistical algorithm is used to allocate tolerance, the distribution type of each composed ring will change the width and intermediate deviation of the closed ring, so that the number of unknown quantities in the allocation process is more than the number of equations, which does not match, resulting in poor accuracy of the interchangeability coordination of panel components.

Obviously, the accompanying drawings in the following description only show some embodiments of the present application, and all other embodiments obtained by those of ordinary skill in the art without any creative effort based on the accompanying drawings should fall within the protection scope of the present application.

It is to be understood that the use of such terms as "including", "comprising", "having" and the like are meant to encompass the inclusion of substances, steps, measures, elements, or components without limiting them to the precise recitation.

[0033] Figure 1 A flowchart of a panel interchangeability design method based on size chain statistics is provided for an embodiment of the application. The embodiment can be applicable to optimizing the interchangeability coordination problem of panel components. The method can be executed by a panel interchangeability design device based on size chain statistics. The panel interchangeability design device based on size chain statistics can be realized in the form of hardware and / or software, and can be configured in a server. As shown in the figure, the method comprises the following steps. Figure 1

[0034] S110, determining the closed loop design parameters of the panel to be interchanged and the corresponding adjacent panel, and a plurality of component ring tolerance parameters.

[0035] The panel to be interchanged refers to any one of the detachable panels on the aircraft body structure, and the adjacent panel refers to the panel adjacent to the position of the panel to be interchanged on the aircraft body structure. For example, in the use process of the aircraft, any one of the detachable panels can be replaced, and the panel to be replaced is the panel to be interchanged. In order to ensure the interchangeability coordination of the aircraft panels, the coordination between different panels needs to be ensured during panel design, which includes the installation coordination of the panel to be interchanged and the gap coordination between the panel to be interchanged and the surrounding adjacent panels. The panel to be interchanged can correspond to one or more adjacent panels. The interchangeability assembly gap requirements are judged for the panel to be interchanged and each adjacent panel in turn. If they all meet the requirements, it means that the related design parameters of the current panel to be interchanged meet the requirements, and the production stage can be carried out. If the aircraft body structure includes a plurality of panels to be interchanged, the interchangeability assembly gap requirements are judged for each panel to be interchanged and the corresponding adjacent panel in turn. If they all meet the requirements, it means that the related design parameters of all the panels to be interchanged meet the requirements, and the production stage can be carried out. Therefore, the technical solution of the present application is in the design stage before the production of the panel to be interchanged, that is, whether the related design parameters of the panel to be interchanged meet the interchangeability assembly gap requirements is determined in the design stage, so as to improve the efficiency and accuracy of panel interchangeability coordination.​

[0036] The closed loop design parameter refers to a gap tolerance related parameter formed after the to-be-interchanged panel and the corresponding adjacent panel are assembled, and for example, the closed loop design parameter at least includes a design nominal gap, which is a theoretical gap value between two adjacent panels in an ideal state according to a functional requirement (such as installation, thermal expansion, sealing or appearance) in a panel assembly butt joint, and is a reference target size of the closed loop in tolerance analysis. The multiple component loop tolerance parameters refer to the sizes of various parts and their tolerances that affect the final assembly result, and for example, at least include hole diameter, hole position, profile, fastener size and the like. For example, the to-be-interchanged panel is connected to the reference member fixed on the body structure through a bolt, and the adjacent panel is also connected to the reference member fixed on the body structure through a bolt, and then the gap between the to-be-interchanged panel and the corresponding adjacent panel is determined by multiple factors such as panel thickness, hole position deviation, bolt diameter, mounting hole size and the like, which are the component loops; the actual gap between the two panels is the closed loop. Among them, the closed loop design parameter is determined according to the design size parameter of the current to-be-interchanged panel, and the component loop tolerance parameter is determined according to the size parameter of the related parts of the body structure.

[0037] S120, constructing a panel interchangeability judgment model according to the closed loop design parameter and the multiple component loop tolerance parameters.

[0038] Based on the closed loop design parameter (such as nominal gap and its allowable tolerance range) and the multiple component loop tolerance parameters (including fastener size, mounting hole diameter and hole position, panel end face profile, and manufacturing and assembly deviation) input by the user, a logical relationship is established through the size chain principle to obtain a panel interchangeability judgment model. The panel interchangeability judgment model is used to judge the matching between the actual gap between the to-be-interchanged panel and the corresponding adjacent panel determined by the multiple component loop tolerance parameters and the closed loop design parameter. The output result of the panel interchangeability judgment model is whether the closed loop design parameter and the multiple component loop tolerance parameters match or not.

[0039] In the panel interchangeability judgment model, the statistical results of the multiple component loop tolerance parameters are compared with the closed loop design parameter, which can comprehensively consider the tolerance cumulative effect of each component loop, predict the gap (i.e. the actual variation range of the closed loop) formed in the actual assembly, and automatically evaluate whether the designed panel assembly can still meet the assembly function requirement under the condition of batch production, so as to judge whether it has the engineering significance of interchangeability.

[0040] In a feasible embodiment, S120 includes:

[0041] According to the multiple component loop tolerance parameters, a gap size chain closed loop tolerance synthesized by the component loop is determined;

[0042] determine the nominal gap tolerance according to the closed loop design parameter and the component ring tolerance parameter;

[0043] construct the panel interchangeability judgment model according to the closed loop tolerance of the gap size chain and the nominal gap tolerance.

[0044] By analyzing all the part sizes and their tolerances that affect the final gap (i.e. component rings), the total tolerance range caused by the accumulation of these tolerances on the final gap (closed loop) is calculated as the closed loop tolerance of the gap size chain. For example, establish a gap size chain model: clearly define the closed loop; identify all part sizes that affect the gap (component rings); determine the direction of each component ring in the size chain (increasing ring or decreasing ring); where increasing ring means that the size increases, and the gap increases; decreasing ring means that the size increases, and the gap decreases. Collect the tolerance parameters of each component ring, such as the nominal size, upper deviation and lower deviation of each component ring, and synthesize the tolerances of each component ring by statistical tolerance method to obtain the closed loop tolerance of the gap size chain.

[0045] The nominal gap tolerance refers to the gap tolerance allocation result used to guide the design or manufacturing under the premise of meeting the closed loop design requirements, that is, the reasonable closed loop tolerance value established based on system analysis. Specifically, based on the known design requirements of the final gap (closed loop design parameter) and the manufacturing tolerances of each part size (component ring tolerance parameter), the design tolerance level that the gap can achieve in assembly is determined through size chain analysis as the nominal gap tolerance.

[0046] The closed loop tolerance of the gap size chain represents the actual tolerance that can be achieved in actual assembly, and the nominal gap tolerance represents the design tolerance determined in combination with the closed loop design parameter. By analyzing the relationship between the closed loop tolerance of the gap size chain and the nominal gap tolerance, the panel interchangeability judgment model is determined, so that the panel interchangeability judgment model can represent the matching of the actual tolerance and the design tolerance.

[0047] The embodiment determines the closed loop tolerance of the gap size chain and the nominal gap tolerance, and constructs the panel interchangeability judgment model according to the relationship between the two, thereby improving the accuracy and calculation efficiency of the panel interchangeability judgment model.

[0048] In a feasible embodiment, the component ring tolerance parameters at least include panel edge parameters of the panel to be interchanged and corresponding adjacent panels, hole group spacing tolerances and corresponding distribution types, tolerances between the panel and the fastener and corresponding distribution types, tolerances between the fastener and the reference part and corresponding distribution types, and tolerances between the panel and the reference hole and corresponding distribution types;

[0049] determine the closed loop tolerance of the gap size chain synthesized by the component rings according to the plurality of component ring tolerance parameters, comprising:

[0050] determining the assembly ring distribution tolerance according to the statistical results of the hole group spacing tolerance and the corresponding distribution type, the panel and fastener tolerance and the corresponding distribution type, the fastener and reference tolerance and the corresponding distribution type, the panel and reference hole tolerance and the corresponding distribution type;

[0051] determining the panel end face edge tolerance according to the panel edge parameters of the to-be-interchanged panel and the corresponding adjacent panel;

[0052] determining the gap size chain closed loop tolerance according to the assembly ring distribution tolerance and the panel end face edge tolerance.

[0053] The panel edge parameters of the to-be-interchanged panel and the corresponding adjacent panel include the maximum thickness of the composite edge of the to-be-interchanged panel and the adjacent panel and the minimum thickness of the composite edge, and the nominal edge thickness is determined according to the average value of the maximum thickness of the composite edge of the two panels and the minimum thickness of the composite edge.

[0054] The hole group spacing tolerance refers to the hole group spacing tolerance of the adjacent panels on the machine structure, and the corresponding distribution type is normal distribution or uniform distribution, and the hole group spacing tolerance is represented as ;

[0055] The panel and fastener tolerance refers to the end face profile of the panel relative to the end face profile of the reference hole, and the corresponding distribution type can be normal distribution, uniform distribution or skewed distribution, the skewed distribution is determined according to the manufacturing, the panel end face manufacturing is biased to the positive tolerance, that is, the skewed (larger) distribution type is selected, and the panel and fastener tolerance is represented as , including and , represents the end face profile of the to-be-interchanged panel end face relative to the end face profile of the reference hole, represents the end face profile of the corresponding adjacent panel end face relative to the end face profile of the reference hole.

[0056] The fastener and reference tolerance refers to the assembly offset between the fastener and the reference on the to-be-installed machine body, and the corresponding distribution type is normal distribution or uniform distribution; the fastener and reference tolerance is represented as and , respectively representing the tolerance between the corresponding fastener and reference of the to-be-interchanged panel and the adjacent panel.

[0057] The panel and reference hole tolerance refers to the assembly offset between the panel and the fastener, and the corresponding distribution type is normal distribution or uniform distribution, and the panel and reference hole tolerance is represented as and , respectively representing the tolerance between the panel and the reference hole of the to-be-interchanged panel and the adjacent panel.

[0058] Exemplarily, the tolerance between the fastener and the reference member and the tolerance between the fastener and the reference member are collectively referred to as The calculation formula can be expressed as: , wherein, represents the maximum diameter of the mounting hole, represents the minimum diameter of the fastener matched with the hole. Exemplarily, represents the difference between the maximum diameter of the mounting hole on the to-be-interchanged panel and the minimum diameter of the fastener matched with the hole. As Figure 2 shows the size of the gap between the to-be-interchanged panel and the corresponding adjacent panel and the reference member.

[0059] Specifically, the hole group spacing tolerance, the tolerance between the panel and the fastener, the tolerance between the fastener and the reference member, and the tolerance between the panel and the reference hole are the influencing factors in the tolerance composition ring, and therefore the statistical tolerance method is used to synthesize each influencing factor to obtain the composition ring distribution tolerance. On this basis, considering that the influence degree of different distribution types of tolerance is different, the corresponding composition ring distribution coefficient is determined according to different distribution types, and the distribution coefficient represents the influence degree of the composition ring on the closed ring, for example, a mapping relationship of the composition ring distribution coefficient corresponding to different distribution types is established in advance. Exemplarily, according to the hole group spacing tolerance and the corresponding distribution type, the tolerance between the panel and the fastener and the corresponding distribution type, the tolerance between the fastener and the reference member and the corresponding distribution type, the tolerance between the panel and the reference hole and the corresponding distribution type, and the mapping relationship, the composition ring distribution coefficient corresponding to the hole group spacing tolerance, the tolerance between the panel and the fastener, the tolerance between the fastener and the reference member, and the tolerance between the panel and the reference hole is determined respectively, and the weighted value of the hole group spacing tolerance, the tolerance between the panel and the fastener, the tolerance between the fastener and the reference member, and the tolerance between the panel and the reference hole and the corresponding composition ring distribution coefficient is taken as the composition ring distribution tolerance. Exemplarily, the composition ring distribution tolerance is expressed as: , wherein, represents the i th composition ring tolerance, which is the hole group spacing tolerance, the tolerance between the panel and the fastener, the tolerance between the fastener and the reference member, and the tolerance between the panel and the reference hole respectively, represents the composition ring distribution coefficient corresponding to the i th composition ring tolerance.

[0060] According to the panel edge sealing parameters of the to-be-interchanged panel and the corresponding adjacent panel, the panel end face sealing tolerance is determined, and specifically, the panel end face sealing tolerance is determined according to the difference between the sum of the maximum thickness of the composite edge sealing and the sum of the minimum thickness of the composite edge sealing. Exemplarily, the panel end face sealing tolerance is determined according to the following formula: ; wherein, represents the maximum thickness of the composite edge sealing of the to-be-interchanged panel, This indicates the maximum thickness of the composite edge banding between adjacent panels. This indicates the minimum thickness of the composite edge banding for the panels to be interchanged. This indicates the minimum thickness of the composite edge banding between adjacent panels. Both the maximum and minimum thickness of the composite edge banding can be obtained directly from the panel's design parameters.

[0061] The tolerance of the closed loop of the gap dimension chain is determined by the sum of the tolerances of the constituent loops and the tolerances of the panel end face sealing. For example, the tolerance of the closed loop of the gap dimension chain is determined according to the following formula. : .

[0062] This embodiment fully considers the influence of each component ring on the closed ring, uses statistical methods to synthesize each component ring, and combines this with the panel end face composite sealing tolerance to improve the accuracy of determining the tolerance of the closed ring in the gap dimension chain.

[0063] In one feasible embodiment, the method further includes, before constructing the panel interchangeability judgment model based on the closed-loop design parameters and the tolerance parameters of multiple component loops:

[0064] Assemblability is checked based on the diameter and location of the mounting holes on the panels to be interchanged and the body structure to be installed.

[0065] The assemblability check is used to verify whether the mounting holes on the interchangeable panel match the corresponding mounting holes on the body structure to be installed. Specifically, it includes verifying the diameter and position information of the mounting holes.

[0066] Specifically, the diameter and location information of the mounting holes for the interchangeable panels are determined, as are the diameter and location information of the mounting holes on the housing structure to be installed. The dimensions of the fasteners corresponding to these mounting holes are also determined. These fasteners, such as screws, are used to secure the interchangeable panels to the housing structure. Based on the diameter information of the mounting holes for the interchangeable panels, the mounting holes on the housing structure to be installed, and the dimensions of the corresponding fasteners, the diameter tolerances are determined. The location tolerances are determined based on the location information of the mounting holes for the interchangeable panels and the mounting holes on the housing structure to be installed. Finally, the assemblability is checked based on the relationship between the diameter tolerances and the location tolerances.

[0067] Exemplarily, the minimum hole diameter of the installation hole of the to-be-interchanged panel, the minimum hole diameter of the installation hole on the to-be-installed body structure, the position tolerance of the installation hole of the to-be-interchanged panel, the hole group position tolerance of the corresponding installation hole of the panel on the to-be-installed body structure, and the maximum fastener diameter of the connection between the panel and the body structure are determined, whether the difference between the sum of the minimum hole diameter of the installation hole of the to-be-interchanged panel and the minimum hole diameter of the installation hole on the to-be-installed body structure and the maximum fastener diameter is greater than or equal to the sum of the position tolerance of the installation hole of the to-be-interchanged panel and the hole group position tolerance of the corresponding installation hole of the panel on the to-be-installed body structure is determined, if yes, it is determined that the assembly check is satisfied, that is, the installation hole meets the assembly requirement, otherwise, the installation hole does not meet the assembly requirement, a design adjustment suggestion is generated, and the process design parameters of the components of the to-be-interchanged panel are adjusted. The position tolerance is a control index for the actual position of a feature deviating from its theoretical position, and the hole group position tolerance of the corresponding installation hole of the panel on the to-be-installed body structure is used to control the overall spatial position (including the absolute position of each hole and the mutual relationship) of the installation hole group on the to-be-installed body structure relative to the geometric tolerance requirement defined by the body reference.

[0068] For example, the assembly check is performed according to the following formula, if the check is successful, it is determined that the check is successful, otherwise, the check fails, wherein, represents the minimum hole diameter of the installation hole of the to-be-interchanged panel, represents the minimum hole diameter of the installation hole on the to-be-installed body structure, represents the position tolerance of the installation hole of the to-be-interchanged panel, represents the hole group position tolerance of the corresponding installation hole of the panel on the to-be-installed body structure, represents the maximum fastener diameter of the connection between the panel and the body structure.

[0069] Before the gap between the to-be-interchanged panel and the adjacent panel is judged, the hole diameter and the position of the installation hole are checked in the embodiment of the application, so as to avoid the error caused by the fact that the installation hole does not meet the requirement after the gap judgment is successful, the installation hole is first judged and adjusted in design, and the efficiency and accuracy of the interchangeability coordination of the to-be-interchanged panel are improved.

[0070] S130, determining whether the current tolerance configuration meets the interchangeability assembly gap requirement according to the judgment result output by the panel interchangeability judgment model.

[0071] If the judgment result output by the panel interchangeability judgment model is that the closed loop design parameter and the component ring tolerance parameter match, it is determined that the current tolerance configuration meets the interchangeability assembly gap requirement. If the judgment result output by the panel interchangeability judgment model is that the closed loop design parameter and the component ring tolerance parameter do not match, it is determined that the current tolerance configuration does not meet the interchangeability assembly gap requirement. The current tolerance configuration at least includes the closed loop design parameter and the related tolerance design parameter of the panel to be interchanged. If the current tolerance configuration meets the interchangeability assembly gap requirement, the design of the panel to be interchanged is completed, and the panel to be interchanged can be produced according to the current tolerance configuration.

[0072] In S140, if the condition is not met, a design adjustment suggestion is generated according to the judgment result.

[0073] If the current tolerance configuration does not meet the interchangeability assembly gap requirement, a design adjustment suggestion is generated according to the judgment result output by the panel interchangeability judgment model. The current tolerance configuration of the panel to be interchanged is modified according to the design adjustment suggestion, and the judgment is continued according to the updated tolerance configuration until the judgment result output by the panel interchangeability judgment model is that the current tolerance configuration meets the interchangeability assembly gap requirement. The design adjustment suggestion is to modify the current tolerance configuration, such as modifying the closed loop design parameter or modifying the related tolerance design parameter of the panel to be interchanged.

[0074] In a feasible embodiment, the design adjustment suggestion is generated according to the judgment result, which includes:

[0075] The design gap upper limit and design gap lower limit adjustment suggestion or the design parameter adjustment suggestion of the panel to be interchanged are generated according to the judgment result.

[0076] The closed loop design parameter at least includes the design gap upper limit and the design gap lower limit. The judgment result output by the panel interchangeability judgment model includes the size comparison result between the closed loop design parameter and the component ring tolerance parameter. According to the size comparison result, the adjustment direction of the design gap upper limit and the adjustment direction and size of the design gap lower limit or the adjustment direction and size of the design parameter of the panel to be interchanged are determined. The adjustment direction includes increasing or decreasing.

[0077] The technical scheme of the embodiment synthesizes the size chain calculation of the panel, constructs the panel interchangeability judgment model according to the closed loop design parameter and the component ring tolerance parameter determined by the user during design, compares the closed loop obtained from the component ring with the input closed loop by the model, determines the interchangeability of the panel, or gives an adjustment suggestion, quickly completes the tolerance coordination between the interchangeable part and the reference part, and optimizes the interchangeability coordination problem of the panel type component.

[0078] Figure 3A flowchart of another panel interchangeability design method based on size chain statistics provided by the embodiments of the present application, the embodiments further refine the selection method of the nominal gap tolerance in the above-mentioned embodiments. As shown in Figure 3 the method comprises:

[0079] S310, determining the closed loop design parameters of the to-be-interchanged panel and the corresponding adjacent panel, and a plurality of component ring tolerance parameters.

[0080] S320, determining the gap size chain closed loop tolerance synthesized by the component ring according to the plurality of component ring tolerance parameters.

[0081] S330, determining the nominal edge thickness according to the panel edge sealing parameters of the to-be-interchanged panel and the corresponding adjacent panel.

[0082] The nominal edge thickness represents the thickness tolerance caused by the panel composite edge sealing. If the panel is a non-composite panel or the original end face does not change after edge sealing, the nominal edge thickness is 0.

[0083] Specifically, since the to-be-interchanged panel and the adjacent panel will be sealed by composite material, since the edge sealing technology will cause the thickness of the panel edge area to be uneven, there is an error in the edge sealing thickness, so it is necessary to determine the nominal edge thickness according to the edge sealing thickness parameters of the adjacent two panels. Exemplarily, the component ring tolerance parameter at least includes the panel edge sealing parameter of the to-be-interchanged panel and the corresponding adjacent panel, the panel edge sealing parameter includes the maximum thickness of the composite edge sealing of the to-be-interchanged panel and the adjacent panel and the minimum thickness of the composite edge sealing, and the nominal edge thickness is determined according to the average value of the maximum thickness of the composite edge sealing of the two panels and the minimum thickness of the composite edge sealing. For example, the nominal edge thickness is determined according to the following formula: wherein, the nominal edge thickness is represented by t, the maximum thickness of the composite edge sealing of the to-be-interchanged panel is represented by t1, the maximum thickness of the composite edge sealing of the adjacent panel is represented by t2, the minimum thickness of the composite edge sealing of the to-be-interchanged panel is represented by t1', the minimum thickness of the composite edge sealing of the adjacent panel is represented by t2', and the maximum thickness of the composite edge sealing of the panel and the minimum thickness of the composite edge sealing can be directly obtained by the design parameters of the panel.

[0084] S340, determining the intermediate deviation according to the panel profile tolerance distribution information of the to-be-interchanged panel and the corresponding adjacent panel.

[0085] The intermediate deviation represents the deviation caused by the asymmetric distribution of the panel end face profile tolerance. If the panel end face profile tolerance is symmetrically distributed, the intermediate deviation is 0.

[0086] Specifically, the ring tolerance parameters at least include face profile tolerance distribution information of the to-be-interchanged panel and the corresponding adjacent panel, the face profile tolerance distribution information includes an end face profile of the to-be-interchanged panel and the adjacent panel relative to a reference hole, and a corresponding end face profile relative asymmetry coefficient is determined according to the end face profile, the coefficient and the end face profile have a fixed and predetermined mapping relationship, and a middle deviation is determined according to a product of the end face profile of the to-be-interchanged panel and the corresponding end face profile relative asymmetry coefficient and an average value of a product of the end face profile of the adjacent panel and the corresponding end face profile relative asymmetry coefficient. Exemplarily, the middle deviation is determined according to the following formula: ; wherein, represents the middle deviation, represents the end face profile of the to-be-interchanged panel, represents the end face profile relative asymmetry coefficient of the to-be-interchanged panel, represents the end face profile of the adjacent panel, represents the end face profile relative asymmetry coefficient of the adjacent panel, and the value of the coefficient can be queried from GB / T 5847-2004.

[0087] S350, determining a reference nominal gap according to the design nominal gap, the design gap upper limit, the design gap lower limit, the nominal edge thickness and the middle deviation, as the nominal gap tolerance.

[0088] The closed ring design parameters include the design nominal gap, the design gap upper limit and the design gap lower limit, the design nominal gap represents a theoretical target gap value between two panels in an ideal design state, the design nominal gap is a theoretical target gap value and does not include a tolerance, for example, is a center or reference point of a tolerance band. The design gap upper limit represents a maximum gap value allowed between two panels on the premise of meeting functional, safety, appearance or performance requirements, and exceeding the value may cause problems. The design gap lower limit represents a minimum gap value allowed between two panels on the premise of ensuring normal assembly, thermal expansion, movement freedom or avoiding interference, and below the value may cause interference, jamming, stress concentration or assembly failure between the panels. The design nominal gap, the design gap upper limit and the design gap lower limit are all set values in the design process.

[0089] Specifically, the reference nominal gap is a comprehensive gap value determined according to the design nominal gap, the design gap upper limit, the design gap lower limit, the nominal edge thickness, and the intermediate deviation, and is used for three-dimensional modeling design of the panels to be interchanged. The reference nominal gap is different from the theoretical gap value of the design nominal gap in a pure sense, and is a standard design gap value determined by comprehensively considering multiple factors. For example, the influence degree and the influence direction of the design nominal gap, the design gap upper limit, the design gap lower limit, the nominal edge thickness, and the intermediate deviation on the reference nominal gap are determined, and the relationship between the reference nominal gap and the above factors is determined according to the influence degree and the influence direction. The specific value of the reference nominal gap is determined according to the relationship.

[0094] If the comparison result output by the panel interchangeability judgment model is that the closed-loop tolerance of the gap size chain is less than or equal to the reference nominal gap, it indicates that the current tolerance configuration meets the interchangeability assembly gap requirement. If the comparison result output by the panel interchangeability judgment model is that the closed-loop tolerance of the gap size chain is greater than the reference nominal gap, it indicates that the current tolerance configuration does not meet the interchangeability assembly gap requirement. That is, the panel interchangeability judgment model is a comparison relationship between and

[0095] Further, in the case where the reference nominal gap cannot be adjusted, if the current tolerance configuration does not meet the interchangeability assembly gap requirement, the design adjustment suggestion generated is to adjust the profile or the connecting hole diameter of the panel to be interchanged, until the design parameters of the panel to be interchanged after adjustment can meet the requirement that the closed-loop tolerance of the gap size chain is less than or equal to the reference nominal gap.

[0100] Figure 4 Another flowchart of a panel interchangeability design method based on size chain statistics provided by the embodiment is provided, and the selection method of the nominal gap tolerance in the above embodiment is further refined. As shown in Figure 4 , the method comprises:

[0101] S410, determining closed-loop design parameters of a panel to be interchanged and corresponding adjacent panels, and a plurality of component ring tolerance parameters.

[0102] S420, determining a closed-loop tolerance of a gap size chain synthesized by the component rings according to the plurality of component ring tolerance parameters.

[0103] S430, determining a design gap tolerance according to a difference between the design gap upper limit and the design gap lower limit.

[0104] The closed-loop design parameters at least include the design gap upper limit and the design gap lower limit, the design gap upper limit represents the maximum gap value allowed between the two panels on the premise of meeting the functional, safety, appearance or performance requirements. The design gap lower limit represents the minimum gap value allowed between the two panels on the premise of ensuring normal assembly, thermal expansion, freedom of movement or avoiding interference.

[0105] The design gap tolerance refers to the difference between the design gap upper limit and the design gap lower limit, and is used to quantify the allowed gap variation range. For example, the design gap tolerance is represented as: , represents the design gap tolerance, represents the design gap upper limit, represents the design gap lower limit.

[0106] S440, determining a nominal edge thickness according to the panel edge parameter of the to-be-interchanged panel and the corresponding adjacent panel.

[0107] The nominal edge thickness represents a thickness tolerance caused by the panel composite edge sealing. If the panel is a non-composite panel or the original end face does not change after the edge sealing, the nominal edge thickness is 0.

[0108] Specifically, since the to-be-interchanged panel and the adjacent panel will be edge sealed by composite materials, the edge sealing technology will cause the thickness of the panel edge region to be uneven, and there will be an error in the edge sealing thickness. Therefore, the nominal edge thickness needs to be determined according to the edge sealing thickness parameters of the two adjacent panels. The specific method for determining the nominal edge thickness can be referred to in the above embodiments, which will not be described here.

[0109] S450, determining a middle deviation according to the face profile tolerance distribution information of the to-be-interchanged panel and the corresponding adjacent panel.

[0110] The middle deviation represents a deviation caused by the asymmetric distribution of the panel end face profile tolerance. If the panel end face profile tolerance is symmetrically distributed, the middle deviation is 0.

[0111] Specifically, the ring tolerance parameter at least includes the face profile tolerance distribution information of the to-be-interchanged panel and the corresponding adjacent panel. The face profile tolerance distribution information includes the end face profile of the to-be-interchanged panel and the adjacent panel relative to the reference hole, and the corresponding end face profile relative asymmetry coefficient is determined according to the end face profile. The coefficient and the end face profile are in a fixed and predetermined mapping relationship. The middle deviation is determined according to the product of the end face profile of the to-be-interchanged panel and the corresponding end face profile relative asymmetry coefficient, and the average value of the product of the end face profile of the adjacent panel and the corresponding end face profile relative asymmetry coefficient. The specific method for determining the middle deviation can be referred to in the above embodiments, which will not be described here.

[0112] S460, determining a target nominal gap upper limit and a target nominal gap lower limit according to the design nominal gap, the nominal edge thickness, the middle deviation, and the gap size chain closed ring tolerance, and taking the design gap tolerance, the target nominal gap upper limit, and the target nominal gap lower limit as the nominal gap tolerance.

[0113] According to the design gap upper limit, the design gap lower limit, the middle deviation, and the nominal edge thickness, the target nominal gap can be determined. The target nominal gap is used to represent the target gap value under the condition of considering the influence of each factor of the ring. From the design effect, the target nominal gap should be as close to the design nominal gap as possible. The design nominal gap represents the theoretical target gap value between the two panels under the ideal design state. The design nominal gap is the theoretical target gap value, which does not include the tolerance. The calculation formula of the target nominal gap is as follows: wherein, represents the target nominal gap.

[0114] Further, since the design nominal gap does not contain tolerance and is an ideal value, and the design process allows a certain degree of tolerance range, the target nominal gap upper limit and the target nominal gap lower limit are determined, and the target nominal gap is located between the target nominal gap upper limit and the target nominal gap lower limit. Specifically, the target nominal gap upper limit represents the maximum value of the target gap under the condition of considering the influence of each factor of the component ring, and the target nominal gap lower limit represents the minimum value of the target gap under the condition of considering the influence of each factor of the component ring. The influence degree and influence direction of the design nominal gap, the nominal edge thickness, the intermediate deviation and the gap size chain closed loop tolerance on the target nominal gap are determined, and the calculation formula of the target nominal gap upper limit and the target nominal gap lower limit is determined according to the relationship between each parameter and the target nominal gap. The calculation formula of the target nominal gap upper limit and the target nominal gap lower limit is as follows: represents the target nominal gap upper limit, represents the target nominal gap lower limit, represents the design nominal gap, represents the nominal edge thickness, represents the intermediate deviation, represents the gap size chain closed loop tolerance.

[0115] S470, according to the gap size chain closed loop tolerance and the nominal gap tolerance, a panel interchangeability judgment model is constructed.

[0116] According to the relationship between the gap size chain closed loop tolerance, the design gap tolerance, the target nominal gap upper limit, the target nominal gap lower limit, the design gap upper limit and the design gap lower limit, the panel interchangeability judgment model is constructed.

[0117] In one possible embodiment, S470, comprising:

[0118] According to the gap size chain closed loop tolerance and the design gap tolerance, a first comparison result is determined;

[0119] According to the target nominal gap upper limit and the design gap upper limit, and the target nominal gap lower limit and the design gap lower limit, a second comparison result is determined;

[0120] According to the first comparison result and the second comparison result, the panel interchangeability judgment model is constructed.

[0121] ​​Firstly, since the design gap tolerance represents the tolerance allowable range between the upper limit of the design gap and the lower limit of the design gap, and the gap size chain closed loop tolerance represents the deviation degree of the comprehensive tolerance determined according to the influencing factors in the composition ring, the first comparison result between the gap size chain closed loop tolerance and the design gap tolerance can reflect the rationality of the current tolerance configuration to a certain extent. Specifically, if the first comparison result is that the gap size chain closed loop tolerance is less than or equal to the design gap tolerance, it means that the deviation degree of the comprehensive tolerance is within the tolerance allowable range, that is, the current tolerance configuration meets the interchangeable assembly gap requirement to a certain extent; if the first comparison result is that the gap size chain closed loop tolerance is greater than the design gap tolerance, it means that the deviation degree of the comprehensive tolerance exceeds the tolerance allowable range, that is, the current tolerance configuration does not meet the interchangeable assembly gap requirement, then the profile tolerance or the connecting hole diameter and other design parameters of the interchangeable panel are adjusted accordingly until the first comparison result is that the gap size chain closed loop tolerance is less than or equal to the design gap tolerance.

[0122] On the basis of the first comparison result that the gap size chain closed loop tolerance is less than or equal to the design gap tolerance, it means that the overall deviation degree of the closed loop determined by the composition ring meets the design requirement, and it is further needed to determine whether the upper and lower limits of the deviation of the closed loop determined by the composition ring meet the design requirement. Specifically, it is determined whether the second comparison result meets the condition that the upper limit of the target nominal gap is less than or equal to the upper limit of the design gap, and the lower limit of the target nominal gap is greater than or equal to the lower limit of the design gap. If it is met, it means that the design nominal gap meets the interchangeability requirement, that is, the current tolerance configuration meets the interchangeable assembly gap requirement, otherwise, it means that the design nominal gap does not meet the interchangeability requirement, and the generated design adjustment suggestion is to adjust the design nominal gap according to the target nominal gap, and to determine again according to the adjusted design nominal gap until the second comparison result meets the condition.

[0123] For example, it is determined that and After that, if the design requirement and is met, that is, and , it means that the design nominal gap L meets the interchangeability requirement, otherwise, it is further needed to adjust the design nominal gap L by referring to .

[0124] The embodiment constructs a panel interchangeability judgment model through the comparison results between the gap size chain closed loop tolerance, the design gap tolerance, the upper limit of the target nominal gap, the lower limit of the target nominal gap, the upper limit of the design gap and the lower limit of the design gap, which improves the accuracy and calculation efficiency of the model construction.

[0126] S490, if not, generating a design adjustment suggestion according to the judgment result.

[0127] The technical scheme of the embodiment can determine whether the interchangeability assembly gap requirement is met through the comparison result between the closed loop tolerance, the design gap tolerance, the upper limit of the target nominal gap, the lower limit of the target nominal gap, the upper limit of the design gap and the lower limit of the design gap in the case that the design nominal gap is adjustable, so that the gap judgment meets the actual tolerance size chain requirement and also meets the design nominal gap related design requirement, and the judgment process is simple, the related design adjustment suggestion can be directly given according to the judgment result, the efficiency and accuracy of the panel interchangeability design judgment are improved, and the link that has a greater impact on interchangeability is quickly identified, so that the generation accuracy of the design adjustment suggestion is improved.
