[0028] Figure 1 is a flow chart of a bracket design method provided in an embodiment of the present invention. This embodiment is applicable to the case of bracket design, and is particularly applicable to the case of bracket design in a front-end cooling module of an automobile. The method can be executed by a bracket design device provided in an embodiment of the present invention, and the device can be implemented in software and / or hardware, and the device can be integrated in an electronic device, and the electronic device can be various user terminals or servers.

[0029] See also Figure 1 The method of the embodiment of the present invention specifically includes the following steps:

[0030] S110, obtaining a three-dimensional module model, wherein the three-dimensional module model is obtained by three-dimensionally modeling a front-end cooling module of an automobile, and the three-dimensional module model includes a bracket modeling result corresponding to a bracket to be designed in the front-end cooling module of the automobile.

[0031] The bracket to be designed is a bracket to be designed. The bracket modeling result is the result of three-dimensional modeling of the bracket to be designed; in the embodiment of the present invention, an initial bracket design scheme can be designed, and when three-dimensional modeling is performed on the front-end cooling module of the automobile, the bracket to be designed can be three-dimensionally modeled according to the design scheme to obtain the bracket modeling result.

[0032] In the embodiment of the present invention, for example, a 3D modeling software may be used to perform preliminary modeling and design on the front-end cooling module of the automobile including the bracket to be designed to obtain a 3D module model. In the embodiment of the present invention, the method for obtaining the 3D module model is not specifically limited.

[0033] In an embodiment of the present invention, the three-dimensional module model may also only include the bracket modeling results corresponding to the bracket to be designed in the automobile front-end cooling module.

[0034] S120, performing random vibration simulation analysis on the three-dimensional module model to obtain a first analysis result, and determining the stress distribution of the bracket to be designed based on the first analysis result.

[0035] The first analysis result is the result of random vibration simulation analysis of the three-dimensional module model; the first analysis result may include, for example, the stress corresponding to each node in the three-dimensional module model or the bracket modeling result, and other contents that can characterize the stress distribution. The first analysis may directly include the stress distribution, and the first analysis result may include at least one of the stress distribution, modal vibration shape, and strain condition, etc. The stress distribution is the stress distribution of the bracket to be designed.

[0036] In the embodiment of the present invention, considering that multiple factors such as time nodes and design and development costs need to be considered in the early stage of development and design, for example, computer-aided engineering (CAE) pre-processing software can be used to perform random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result. In the embodiment of the present invention, the method of performing random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result is not specifically limited.

[0037] In the embodiment of the present invention, for example, the first analysis result can be determined by solving the motion equation. Specifically, considering that the stress of the three-dimensional module model is based on the external random load excitation, the motion equation can be used. Element mass matrix, element stiffness matrix And the element damping matrix The displacement vector a(t) of each node in the three-dimensional module model or the bracket modeling result is calculated, where: a(t) is the node acceleration vector, node velocity vector and node displacement vector of the three-dimensional module model, M, C, K, Q(t) are the mass matrix, damping matrix, stiffness matrix and node load vector of the three-dimensional module model, M, C, K, Q(t) are respectively composed of their own unit matrices and vectors, ρ is the mass density, N is the shape function matrix, D is the elastic matrix, B is the strain matrix, μ is the damping coefficient, V is the calculation area, that is, the area of ​​the three-dimensional module model or the bracket modeling result. It should be noted that the variables required for the above calculation process can be directly obtained; according to the displacement vector a(t) of each node, through the equilibrium equation σ ji,j +f i -ρu i,tt -μu i,t = 0 (in the V domain), determine the stress σ corresponding to each node in the three-dimensional module model or the bracket modeling result, where σ ji,j is stress, f i is the force, u i,tt and u i,t u i The second and first derivatives with respect to t, ρu i,tt and μu i,t They represent inertia force and damping force respectively, i and j represent i direction and j direction respectively. It should be noted that the variables required for the above calculation process can be directly obtained; according to the stress σ corresponding to each node, the first analysis result is determined.

[0038] In the embodiment of the present invention, for example, the stresses corresponding to each node in the three-dimensional module model in the first analysis result or the bracket modeling result can be summarized and analyzed to obtain the stress distribution; for another example, the stress analysis in the first analysis result can be directly used as the stress distribution of the bracket to be designed; for another example, the stress concentration part can be determined according to the first analysis result, and the stress concentration part can be used as the stress distribution; for another example, each target stress value exceeding the preset stress threshold can be determined according to the first analysis result, and the stress distribution can be determined according to each target stress value; etc. In the embodiment of the present invention, the method of determining the stress distribution of the bracket to be designed according to the first analysis result is not specifically limited.

[0039] S130. Determine a stent design result of the stent to be designed according to the stress distribution and the stent modeling result.

[0040] Among them, the stent design result is the result obtained by designing the stent to be designed; the stent design result can be in the form of a model, or in the form of a stent design scheme, etc. In the embodiment of the present invention, there is no specific limitation on the form of expression of the stent design result.

[0041] In an embodiment of the present invention, for example, the stress distribution can be evaluated according to the stress limit standard in the bracket design requirements. When the stress distribution meets the stress limit standard, the bracket modeling result is used as the bracket design result; when the stress distribution does not meet the stress limit standard, the bracket modeling result is adjusted, and a random vibration simulation analysis is performed on the three-dimensional module model to obtain a first analysis result, until the stress distribution meets the stress limit standard. In an embodiment of the present invention, the method of determining the bracket design result of the bracket to be designed based on the stress distribution and the bracket modeling result is not specifically limited.

[0042] In the embodiment of the present invention, the stress distribution and strain of the bracket to be designed can also be determined according to the first analysis result. Specifically, considering that the strain of the three-dimensional module model is based on the external random load excitation, the geometric equation (i, j = 1, 2, 3) (in the V domain), calculate the strain of each node in the three-dimensional module model or bracket modeling result, where ε ij is strain; u i,j and u j,i They are all displacement components. It should be noted that the variables required for the above calculation process can be directly obtained; according to the strain corresponding to each node, the first analysis result is determined; according to the stress distribution, strain and bracket modeling results, the bracket design result of the bracket to be designed is determined.

[0043] In an embodiment of the present invention, the modal vibration shape of the three-dimensional module model can also be determined based on the first analysis result; the bracket design result of the bracket to be designed can be determined based on at least one of the strain condition, stress distribution condition and modal vibration shape, as well as the bracket modeling result.

[0044] In an embodiment of the present invention, the stent design result is determined by the stress distribution and the stent modeling result, so that a stent design result with a more reasonable stress distribution can be obtained within a shorter development and design time cycle, thereby ensuring the stability and reliability of the stent manufactured according to the stent design result.

[0045] The technical solution of the embodiment of the present invention is obtained by obtaining a three-dimensional module model, wherein the three-dimensional module model is obtained by three-dimensional modeling of the automobile front-end cooling module, and the three-dimensional module model includes a bracket modeling result corresponding to the bracket to be designed in the automobile front-end cooling module, so as to obtain a three-dimensional module model for the automobile front-end cooling module; by performing random vibration simulation analysis on the three-dimensional module model, a first analysis result is obtained, and based on the first analysis result, the stress distribution of the bracket to be designed is determined, so as to obtain a stress distribution that can characterize whether the bracket modeling result is stable; by determining the bracket design result of the bracket to be designed based on the stress distribution and the bracket modeling result, the bracket design is realized. The above technical solution determines the bracket design result through the stress distribution and the bracket modeling result, so as to obtain a bracket design result with a more reasonable stress distribution, thereby ensuring the stability of the bracket.

[0046] An optional technical solution, a bracket design method, also includes: determining the modal vibration shape of the three-dimensional module model based on the first analysis result; determining the bracket design result of the bracket to be designed based on the stress distribution and the bracket modeling result, including: determining the bracket design result of the bracket to be designed based on the stress distribution, the modal vibration shape and the bracket modeling result.

[0047] The mode shape is the vibration form of the three-dimensional module model at a specific natural frequency.

[0048] It is understandable that both the modal vibration shape and the stress distribution can be used to compare the feasibility of the three-dimensional module model. Therefore, the bracket design result of the bracket to be designed can be determined based on the stress distribution, the modal vibration shape and the bracket modeling results.

[0049] In an embodiment of the present invention, for example, the stress distribution can be evaluated according to the stress requirements, and the modal vibration shape can be evaluated according to the modal vibration shape requirements. When the stress distribution meets the stress requirements and the modal vibration shape meets the modal vibration shape requirements, the bracket modeling result is used as the bracket design result; when the stress distribution does not meet the stress requirements or the modal vibration shape does not meet the modal vibration shape requirements, the bracket modeling result is adjusted, and a random vibration simulation analysis is performed on the three-dimensional module model to obtain a first analysis result, until the stress distribution meets the stress requirements and the modal vibration shape meets the modal vibration shape requirements. In an embodiment of the present invention, there is no specific limitation on the method of determining the bracket design result of the bracket to be designed based on the stress distribution, the modal vibration shape and the bracket modeling result.

[0050] In the embodiment of the present invention, by determining the bracket design result of the bracket to be designed according to the stress distribution, the modal vibration shape and the bracket modeling result, a more refined bracket design result can be obtained, thereby further ensuring the stability of the bracket.

[0051] Another optional technical solution is that before performing random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result, the bracket design method also includes: performing mesh division pre-processing on the three-dimensional module model, and updating the three-dimensional module model according to the obtained division result.

[0052] The division result is obtained by pre-processing the mesh division of the three-dimensional module model.

[0053] In the embodiment of the present invention, for example, CAE pre-processing software can be used to perform mesh pre-processing on the three-dimensional module model. In the embodiment of the present invention, the method of performing mesh pre-processing on the three-dimensional module model is not specifically limited.

[0054] In an embodiment of the present invention, when it is required to simplify the modeling results to be simplified in the three-dimensional module model, the three-dimensional module model can be subjected to mesh pre-processing before random vibration simulation analysis is performed on the three-dimensional module model to obtain the second analysis result, and the three-dimensional module model can be updated based on the obtained meshing result; after the three-dimensional module model is updated based on the obtained simplified result, and when the bracket modeling result has not been adjusted, the bracket modeling result can be meshed reconstructed using finite element pre-processing software or the like, and the three-dimensional module model can be updated based on the mesh reconstruction result.

[0055] In the embodiment of the present invention, by performing mesh division pre-processing on the three-dimensional module model, the computational efficiency of calculating the first analysis result can be improved.

[0056] Figure 2 It is a flow chart of another stent design method provided in an embodiment of the present invention. This embodiment is designed based on the above-mentioned technical solutions. In this embodiment, optionally, the stent design result of the stent to be designed is determined according to the stress distribution and the stent modeling result, including: when the stress distribution meets the preset stress requirements, the stent modeling result is used as the stent design result of the stent to be designed. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0057] See also Figure 2 The method of this embodiment may specifically include the following steps:

[0058] S210, obtaining a three-dimensional module model, wherein the three-dimensional module model is obtained by three-dimensionally modeling a front-end cooling module of an automobile, and the three-dimensional module model includes a bracket modeling result corresponding to a bracket to be designed in the front-end cooling module of the automobile.

[0059] S220, performing random vibration simulation analysis on the three-dimensional module model to obtain a first analysis result, and determining the stress distribution of the bracket to be designed based on the first analysis result.

[0060] S230. When the stress distribution meets the preset stress requirement, the bracket modeling result is used as the bracket design result of the bracket to be designed.

[0061] Among them, the stress requirement is the requirement that the stress distribution must meet when the bracket modeling result is used as the bracket design result; the stress requirement can be, for example, at least one of the standard range of stress values, the stress limit standard, and the standard range of stress concentration locations, etc.

[0062] It is understandable that when the stress distribution meets the preset stress requirements, it means that the stress distribution of the stent modeling result is relatively reasonable, so the stent modeling result can be used as the stent design result of the stent to be designed.

[0063] The technical solution of the embodiment of the present invention, by using the bracket modeling result as the bracket design result of the bracket to be designed when the stress distribution meets the preset stress requirements, can make the stress distribution of the bracket manufactured according to the bracket design result more reasonable, thereby ensuring the stability of the bracket.

[0064] Figure 3 It is a flow chart of another bracket design method provided in an embodiment of the present invention. This embodiment is designed based on the above-mentioned technical solutions. In this embodiment, optionally, the bracket design result of the bracket to be designed is determined according to the stress distribution and the bracket modeling result, and also includes: when the stress distribution does not meet the stress requirement, adjusting the bracket modeling result, and updating the bracket modeling result according to the obtained adjustment result; repeating the step of performing random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0065] See also Figure 3 The method of this embodiment may specifically include the following steps:

[0066] S310, obtaining a three-dimensional module model, wherein the three-dimensional module model is obtained by three-dimensionally modeling a front-end cooling module of an automobile, and the three-dimensional module model includes a bracket modeling result corresponding to a bracket to be designed in the front-end cooling module of the automobile.

[0067] S320, performing random vibration simulation analysis on the three-dimensional module model to obtain a first analysis result, and determining the stress distribution of the bracket to be designed based on the first analysis result.

[0068] S330. When the stress distribution meets the preset stress requirement, the bracket modeling result is used as the bracket design result of the bracket to be designed.

[0069] S340. When the stress distribution does not meet the stress requirement, adjust the support modeling result, and update the support modeling result according to the obtained adjustment result, and return to execute S320.

[0070] Among them, the adjustment result is the result obtained after adjusting the bracket modeling result.

[0071] In an embodiment of the present invention, for example, when the stress distribution does not meet the stress requirement, the distance between the center of the bolt hole and the leftmost side of the U-shaped groove and / or the distance between the center of the bolt hole and the rightmost side of the U-shaped groove in the bracket modeling result is adjusted, and the bracket modeling result is updated according to the obtained adjustment result. In an embodiment of the present invention, the method for adjusting the bracket modeling result is not specifically limited.

[0072] The technical solution of the embodiment of the present invention adjusts the bracket modeling result when the stress distribution does not meet the stress requirement, and repeatedly performs random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result, so that the stress distribution of the bracket manufactured by the final adjusted bracket modeling result is more reasonable, thereby ensuring the stability of the bracket.

[0073] An optional technical solution for adjusting the support modeling result includes: determining the stress concentration location in the support modeling result according to the stress distribution; and adjusting the stress concentration location.

[0074] Among them, the stress concentration location is the location where stress is concentrated in the bracket modeling results.

[0075] In the embodiment of the present invention, for example, based on the stress distribution, the portion corresponding to the stress exceeding the preset stress threshold in the stent modeling result can be used as the stress concentration portion. In the embodiment of the present invention, the method for determining the stress concentration portion in the stent modeling result based on the stress distribution is not specifically limited.

[0076] In the embodiment of the present invention, the structure of the stress concentration part can be modified and optimized to adjust the stress concentration part. In the embodiment of the present invention, the method of adjusting the stress concentration part is not specifically limited.

[0077] Exemplarily, based on the stress distribution, it is determined that the stress concentration area in the bracket modeling results is mainly near the bolt hole position. Therefore, the adjustment of the bracket modeling results mainly takes into account the strain and / or stress around the bolt hole, and adjusts the position relationship between the U-shaped groove and the bolt hole near the bolt hole position in the bracket modeling results.

[0078] In the embodiment of the present invention, by adjusting the stress concentration position, the stress distribution of the stent manufactured by the final adjusted stent modeling result can be further made more reasonable, thereby further ensuring the stability of the stent.

[0079] Figure 4 It is a flow chart of another bracket design method provided in an embodiment of the present invention. This embodiment is designed based on the above-mentioned technical solutions. In this embodiment, optionally, before performing random vibration simulation analysis on the three-dimensional module model to obtain a first analysis result, the bracket design method also includes: obtaining the connection relationship between the components in the front-end cooling module of the automobile; performing random vibration simulation analysis on the three-dimensional module model to obtain a second analysis result; simplifying the modeling results to be simplified in the three-dimensional module model according to the second analysis result and the connection relationship, and updating the three-dimensional module model according to the obtained simplified results. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0080] See also Figure 4 The method of this embodiment may specifically include the following steps:

[0081] S410, obtaining a three-dimensional module model, wherein the three-dimensional module model is obtained by three-dimensionally modeling a front-end cooling module of an automobile, and the three-dimensional module model includes a bracket modeling result corresponding to a bracket to be designed in the front-end cooling module of the automobile.

[0082] S420, obtaining the connection relationship between the components in the front-end cooling module of the automobile.

[0083] The components are the various parts that make up the front-end cooling module of the automobile; the components may be, for example, a high-temperature radiator, a low-temperature radiator, a condenser, a fan assembly, a bracket, etc. The connection relationship is the interconnection relationship between the components.

[0084] S430: Simplify the modeling results to be simplified in the three-dimensional module model according to the connection relationship, and update the three-dimensional module model according to the obtained simplified results.

[0085] The modeling result to be simplified is the result obtained by three-dimensional modeling of the component to be simplified; the component to be simplified may be, for example, at least one of a fan assembly, a low-temperature radiator, and a condenser, etc., and the corresponding modeling result to be simplified may include partial modeling results corresponding to at least one of the fan assembly, the low-temperature radiator, and the condenser, etc. The simplified result is the result obtained by simplifying the modeling result to be simplified in the three-dimensional module model.

[0086] It should be noted that, considering that the current bracket is usually a structure of installing the front-end module using a plastic frame made of plastic injection molding, but the strength of this bracket structure is poor, and it is easy to break and damage when subjected to external alternating loads, thereby affecting the normal operation of the front-end cooling module, and in order to cooperate with the installation of cooling components such as radiators and fans, its frame structure is complex, not easy to disassemble, and the design and manufacturing cost is high. At the same time, later disassembly and maintenance are relatively difficult. Therefore, the bracket to be designed can be a steel bracket to be designed to reduce the overall manufacturing, use, and maintenance costs during the life cycle. However, for the bracket of the steel structure, under the condition of taking into account both the cost and the structural stability, its preliminary design needs to be repeatedly tested and verified. For example, if the stress distribution does not meet the stress requirements, the random vibration simulation analysis of the three-dimensional module model will be repeated to obtain the process of the first analysis result, and the process is relatively complicated. The number of grids in the three-dimensional module model is huge, resulting in a high time cycle and cost for the bracket design. For this reason, in an embodiment of the present invention, the development time cycle and cost of the bracket design can be reduced by simplifying the three-dimensional module model.

[0087] In an embodiment of the present invention, the front-end cooling module may include components such as a high-temperature radiator, a low-temperature radiator, a condenser, a fan assembly, and a bracket. Accordingly, the three-dimensional module model may include partial modeling results corresponding to the high-temperature radiator, the low-temperature radiator, the condenser, the fan assembly, and the bracket, that is, the bracket modeling result is the partial modeling result corresponding to the bracket; for example, it can be determined based on the connection relationship that the fan assembly, the low-temperature radiator, and the condenser are rigidly connected to the steel bracket. Therefore, the partial modeling results corresponding to the fan assembly, the low-temperature radiator, and the condenser can be used as the modeling results to be simplified, and the modeling results to be simplified are simplified into at least one mass point, and then at least one mass point is rigidly connected to the bracket modeling result, thereby simplifying the mass matrix, stiffness matrix, and damping matrix inside the front-end cooling module, and can greatly improve the calculation speed and efficiency, saving time and development costs for the early development design. In an embodiment of the present invention, there is no specific limitation on the method of simplifying the modeling results to be simplified in the three-dimensional module model based on the connection relationship.

[0088] In an embodiment of the present invention, a random vibration simulation analysis can also be performed on the three-dimensional module model to obtain a second analysis result. According to the connection relationship and the second analysis result, the modeling result to be simplified in the three-dimensional module model is simplified, and according to the obtained simplified result, the three-dimensional module model is updated. For example, according to the connection relationship, it can be determined that the fan assembly, the low-temperature radiator and the condenser are all rigidly connected to the steel support. The partial modeling results corresponding to the fan assembly, the low-temperature radiator and the condenser are used as the modeling results to be simplified, and the modeling result to be simplified is simplified into at least one mass point. According to the second analysis result, at least one mass point is rigidly connected to the support modeling result.

[0089] It is understandable that before performing random vibration simulation analysis on the three-dimensional module model and obtaining the first analysis result, the three-dimensional module model may be pre-processed for meshing and the three-dimensional module model may be simplified, which can reduce the number of meshes by about 2 / 3. Therefore, the technical solution of the embodiment of the present invention can greatly improve the computing efficiency and greatly shorten the early development and design cycle.

[0092] S460. When the stress distribution does not meet the stress requirement, adjust the support modeling result, and update the support modeling result according to the obtained adjustment result, and return to execute S440.

[0093] The technical solution of the embodiment of the present invention simplifies the modeling results to be simplified in the three-dimensional module model according to the connection relationship, so as to greatly improve the calculation efficiency and greatly shorten the early development and design cycle.

[0094] An optional technical solution, a bracket design method, before updating the three-dimensional module model according to the simplified result obtained, also includes: obtaining a preset damping coefficient; performing random vibration simulation analysis on the three-dimensional module model to obtain a second analysis result; performing random vibration simulation analysis on the three-dimensional module model to obtain a first analysis result, including: performing random vibration simulation analysis on the three-dimensional module model according to the damping coefficient to obtain the first analysis result; after performing random vibration simulation analysis on the three-dimensional module model according to the damping coefficient to obtain the first analysis result, it also includes: when the bracket modeling result has not been adjusted, performing a consistency check on the first analysis result and the second analysis result; when the obtained test result indicates that the first analysis result and the second analysis result are inconsistent, adjusting the damping coefficient, and repeating the step of performing random vibration simulation analysis on the three-dimensional module model according to the damping coefficient to obtain the first analysis result.

[0095] Among them, the damping coefficient is a parameter of energy dissipation characteristics, which is usually used in vibration analysis and control design. The second analysis result is the result obtained by performing random vibration simulation analysis on the three-dimensional module model. The test result is the result obtained by performing consistency test on the first analysis result and the second analysis result, which can indicate whether the first analysis result and the second analysis result are consistent.

[0096] In the embodiment of the present invention, for example, random vibration simulation analysis can be performed on the three-dimensional module model according to the damping coefficient to obtain a second analysis result. In the embodiment of the present invention, the manner of performing random vibration simulation analysis on the three-dimensional module model to obtain the second analysis result may be the same as or different from the manner of performing random vibration simulation analysis on the three-dimensional module model to obtain the first analysis result. In the embodiment of the present invention, the manner of performing random vibration simulation analysis on the three-dimensional module model to obtain the second analysis result is not specifically limited.

[0097] In the embodiment of the present invention, for example, the three-dimensional module model can be subjected to random vibration simulation analysis by combining the motion equation and the equilibrium equation with the damping coefficient to obtain the first analysis result. In the embodiment of the present invention, the manner of performing random vibration simulation analysis on the three-dimensional module model according to the damping coefficient to obtain the first analysis result is not specifically limited.

[0098] In an embodiment of the present invention, when the bracket modeling result has not been adjusted, it means that the damping coefficient suitable for the simplified three-dimensional module model may not have been determined yet. Therefore, the first analysis result and the second analysis result can be checked for consistency; when the obtained test result indicates that the first analysis result and the second analysis result are inconsistent, it means that the current damping coefficient is not suitable for the simplified three-dimensional module model, the damping coefficient is adjusted, and the step of performing random vibration simulation analysis on the three-dimensional module model according to the damping coefficient to obtain the first analysis result is repeated to verify again whether the damping coefficient suitable for the simplified three-dimensional module model is determined; when the obtained test result indicates that the first analysis result and the second analysis result are consistent, it means that the current damping coefficient is suitable for the simplified three-dimensional module model, and the first analysis result calculated according to the damping coefficient can be used in the subsequent process of obtaining the bracket design result.

[0099] In an embodiment of the present invention, by adjusting the damping coefficient, the influence of the damping coefficient on the mass matrix, stiffness matrix and damping matrix of the overall three-dimensional module model can be reduced, thereby reducing the error before and after the simplification of the three-dimensional module model, thereby improving the accuracy of the bracket design using the simplified three-dimensional module model.

[0100] In order to better understand the technical solution of the above embodiment of the present invention, an optional example is provided here. Figure 5, perform preliminary design 3D modeling and CAE simulation analysis on the front-end cooling module of the automobile, and obtain a second analysis result that can characterize the modal vibration shape and stress distribution; according to the motion equations and connection relationships solved by CAE simulation, simplify the simplified modeling results corresponding to the fan assembly, condenser and low-temperature radiator into mass points respectively, so as to simplify the simplified modeling results corresponding to the low-temperature radiator, condenser and fan assembly in the 3D module model of the front-end cooling module, and update the 3D module model according to the simplified results obtained, for example, see Figure 6 The simplified three-dimensional module model includes the bracket modeling result 100, the water inlet chamber 200 of the partial modeling result corresponding to the high-temperature radiator, the water outlet chamber 300 of the partial modeling result corresponding to the high-temperature radiator, the partial modeling result corresponding to the fan assembly simplified as the mass point G1, and the partial modeling result corresponding to the low-temperature radiator and the simplified mass point of the partial modeling result corresponding to the condenser simplified as the mass point G2. The water inlet chamber 200 of the partial modeling result corresponding to the high-temperature radiator and the water outlet chamber 300 of the partial modeling result corresponding to the high-temperature radiator are respectively connected to the threaded holes at both ends of the bracket modeling result 100 by bolts, and the masses G1 and G2 are connected by establishing a rigid connection unit (RigidBody Element 2, RBE2) is connected to the bolt holes on the front and rear sides of the bracket modeling result 100, the three-dimensional module model also includes an installation arm 110, the bracket modeling result 100 is connected to the installation arm 110 by riveting, the three-dimensional module model also includes a water chamber mounting support 210 of the partial modeling result corresponding to the high-temperature radiator, the water inlet chamber 200 of the partial modeling result corresponding to the high-temperature radiator and the water chamber mounting support 210 of the partial modeling result corresponding to the high-temperature radiator are molded by integral injection molding, and the three-dimensional module model is assembled to the vehicle frame through the installation arm 110 and the water chamber mounting support 210 of the partial modeling result corresponding to the high-temperature radiator; the three-dimensional module model is subjected to CAE simulation analysis again to obtain the first analysis result that can characterize the modal vibration shape and stress distribution. It should be noted that compared The CAE simulation analysis of the second analysis result is obtained. Since the number of grids of the simplified three-dimensional module model is reduced, its calculation rate is significantly improved accordingly; when the bracket modeling result has not been adjusted, the modal vibration shape and stress distribution in the first analysis result and the modal vibration shape and stress distribution in the second analysis result are checked for consistency. When the obtained test result indicates that the first analysis result and the second analysis result are inconsistent, the damping coefficient is adjusted, and the CAE simulation analysis of the three-dimensional module model is performed again to obtain the first analysis result that can characterize the modal vibration shape and stress distribution, so as to reduce the error before and after the simplification of the three-dimensional module model and ensure consistency; according to the stress distribution in the first analysis result, the stress concentration location in the bracket modeling result is determined, for example, see Figure 7 and Figure 8The stress concentration locations are mainly the bolt holes 101 and the vicinity of the U-shaped grooves 104 on the front and rear sides of the bracket modeling result 100 and the vicinity of the riveting position between the bracket modeling result 100 and the mounting arm 110. For the convenience of description, the stress concentration locations are respectively labeled as L1, L2, L3, L4 and L5; through the stress concentration locations, it is judged whether the stress distribution is within the standard range; if it is not within the standard range, it means that there is still a lot of room for improvement in the bracket modeling result, and the stress concentration locations are locally modified and optimized, for example, see Figure 6 and Fig. 9 According to the stress distribution, it is determined that the stress exceeds the limit in the standard range or the stress risk coefficient is high on the fillet near the mounting arm 110 in the four U-shaped grooves 104 at the stress concentration location, that is, the first fillet 102 and the second fillet 103 are the main risk locations. Specifically, the distance d1 between the center of the bolt hole 101 and the leftmost side of the U-shaped groove 104 and the distance d2 between the center of the bolt hole 101 and the rightmost side of the U-shaped groove 104 can be changed, thereby directing the concentrated stress to the middle part of the bracket modeling result 100 as much as possible, thereby reducing the risk of failure of the stress concentration location; then, the finite element pre-processing software is used to reconstruct the mesh of the locally modified and optimized part of the steel bracket, and the three-dimensional module model is updated according to the obtained mesh reconstruction result, and the step of performing CAE simulation analysis on the three-dimensional module model again to obtain the first analysis result that can characterize the modal vibration shape and stress distribution is repeated until the stress distribution is within the standard range, and the bracket modeling result is used as the bracket design result of the bracket to be designed, for example, see Fig.10 , by repeatedly executing the CAE simulation analysis on the three-dimensional module model again, the first analysis result that can characterize the modal vibration shape and stress distribution is obtained. Finally, when the distance d1 between the center of the bolt hole 101 and the leftmost side of the U-shaped groove 104 is about 2.5 times the width d0 of the U-shaped groove, and the distance d2 between the center of the bolt hole 101 and the rightmost side of the U-shaped groove 104 is about 1.5 times the width d0 of the U-shaped groove, the maximum stress at the positions L1, L2, L4 and L5 on the bracket modeling result 100 is greatly improved in three directions. Due to the change in the structure, the local stress is transferred, and L 3 has slightly increased, but the overall maximum stress values ​​of each part in the bracket modeling result 100 have been well improved, and the maximum stresses of each main stress concentration part are all within the standard range, the overall risk factor is reduced, and the stability and reliability of the bracket manufactured by the bracket modeling result are effectively improved, thereby obtaining a bracket with simple structure, easy processing, simple connection method, and better connection stability and durability; the three-dimensional module model is exported, and the sample of the automobile front-end cooling module corresponding to the three-dimensional module model or the bracket to be designed corresponding to the bracket design result is processed for experimental verification.

[0101] The above-mentioned technical scheme of the embodiment of the present invention performs bracket design based on CAE simulation, which can realize rapid acquisition of stress concentration locations within a relatively short development and design time cycle, and modify and optimize the bracket modeling results, and then repeat the CAE random vibration simulation analysis, which can fully take into account the stress conditions of various parts of the bracket modeling results and reduce the risk of stress concentration. By simplifying the simplified modeling results, the number of grids can be reduced by about 2 / 3, thereby greatly shortening the design and development cycle of the bracket to be designed, and improving the stability and reliability of the bracket design results, thereby improving the stability and reliability of the designed bracket, and then improving the stability and reliability of the automobile front-end cooling module, thereby reducing the overall design, manufacturing, use and maintenance costs of the bracket during its life cycle.
