Description

Technical Field

[0001] This application relates to the technical field of sealing performance analysis, and in particular, to a sealing performance simulation test method, an electronic device, and a non-volatile computer-readable storage medium. Background Art

[0002] In the existing simulation test for the sealing performance of a component under test, the sealing ring of the component under test is usually not accurately modeled, and only the two-dimensional cross-section of the sealing ring is simulated and modeled. A uniformly distributed surface pressure is applied to the plane (groove surface) of the component under test where the groove for placing the sealing ring is provided, and the displacement of the groove surface is calculated to obtain the sealing performance of the component under test.

[0003] However, during the simulation test, the magnitude of the surface pressure applied to different components under test is usually fixed and unchanged, and the magnitude of the surface pressure is not adjusted based on the cross-sectional shape of the sealing ring, the length of the sealing ring, and the positions of fasteners such as bolts in the component under test. Therefore, the sealing performance simulation test method of applying a uniformly distributed surface pressure to the component under test often results in a large difference between the simulation result and the actual situation, and there is a problem that the simulation test is not accurate enough.

[0051] Please refer to Figures 2 to 4 , Figure 2 which is a schematic flowchart of an embodiment of the sealing performance simulation test method provided by this application, Figure 3 and Figure 2 is a schematic structural diagram of an embodiment of the three-dimensional model of the component to be measured shown in Figure 4 and Figure 2 is a top view of an embodiment of the three-dimensional model of the component to be measured shown in . The sealing performance simulation test method is used to perform a simulation test on any of the above-mentioned components 1 to be measured to determine the sealing performance of the component 1 to be measured. The sealing performance simulation test method includes the following steps.

[0052] Step S101, obtain the three-dimensional model of the component to be measured.

[0053] The component 1 to be measured includes a fixing member 11 and a sealing member 13. The fixing member 11 is provided with a groove 110, and the sealing member 13 is accommodated in the groove 110. The three-dimensional model of the component 1 to be measured is a model constructed based on the component 1 to be measured, such as a Finite Element Analysis (FEA) model. Therefore, the specific structure of the three-dimensional model of the component 1 to be measured is basically the same as the specific structure of the above-mentioned component 1 to be measured.

[0054] In some embodiments, the surface of the fixing member 11 provided with the groove 110 is the sealing surface 111. The component to be tested 1 further includes a connecting member 12 fixed to the fixing member 11. The connecting member 12 includes a first section 121 and a second section 122. The first section 121 extends from the sealing surface 111 in a direction perpendicular to the sealing surface 111, and the second section 122 extends in a direction parallel to the sealing surface 111. It can be understood that during the simulation test, the fixing member 11 refers to the three-dimensional model of the fixing member 11, the sealing member 13 refers to the three-dimensional model of the sealing member 13, and the connecting member 12 refers to the three-dimensional model of the connecting member 12. That is to say, all components of the component to be tested 1 described during the simulation test refer to the three-dimensional model, which will not be elaborated hereinafter.

[0055] Step S102: Apply a displacement to the three-dimensional model of the component to be tested to generate a displacement value of the groove.

[0056] Based on different pre-set working conditions, displacements are applied to different components of the three-dimensional model of the component to be tested 1, such as the sealing member 13 and the connecting member 12, so as to generate displacement values of the groove 110 under different working conditions. Among them, different working conditions include, but are not limited to, the working condition without considering the installation tolerance of the connecting member 12 and the working condition considering the installation tolerance of the connecting member 12.

[0057] Step S103: Determine the sealing performance of the component to be tested based on the displacement value, the depth of the groove, and the height of the sealing member.

[0058] Obtain the depth of the groove 110 and the height of the sealing member 13, and judge whether the sealing performance of the component to be tested 1 is reliable based on the displacement value, the depth of the groove 110, and the height of the sealing member 13.

[0059] For the sealing performance simulation method of the present application, a three-dimensional model of the component to be tested 1 is obtained. The component to be tested 1 includes a fixing member 11 and a sealing member 13. The fixing member 11 is provided with a groove 110, and the sealing member 13 is accommodated in the groove 110; a displacement is applied to the three-dimensional model of the component to be tested 1 to generate a displacement value of the groove 110; the sealing performance of the component to be tested 1 is determined based on the displacement value, the depth of the groove 110, and the height of the sealing member 13; the three-dimensional model of the component to be tested 1 corresponds to the component to be tested 1, and can perform simulation tests on different components to be tested 1 specifically. During the process of applying a displacement to the three-dimensional model of the component to be tested 1, the sealing member 13 is located in the groove 110, and the deformation of the groove 110 can be accurately simulated, so as to obtain an accurate displacement value of the groove 110, thereby improving the accuracy of the sealing performance simulation test.

[0060] Please refer to Figure 5 , Figure 5 is Figure 2 a schematic flowchart of an embodiment of step S101 in

[0061] Step S201, obtain the fixing member, the sealing member, and the connecting member.

[0062] Obtaining the fixing member 11, the sealing member 13, and the connecting member 12 means obtaining the three-dimensional models of the fixing member 11, the sealing member 13, and the connecting member 12. Among them, both the fixing member 11 and the connecting member 12 can be second-order tetrahedral elements C3D10M with 10 nodes, and the sealing member 13 can be a hexahedral hybrid element C3D8RH with 8 nodes.

[0063] In some embodiments, the user environment of HyperMesh is adjusted to the Abaqus environment. The fixing member 11, the sealing member 13, and the connecting member 12 can be imported into HyperMesh in the form of geometric digital models in stp format, and meshing is performed on the fixing member 11, the sealing member 13, and the connecting member 12.

[0064] Step S202, set the material properties of the fixing member, the sealing member, and the connecting member.

[0065] The material property of the fixing member 11 can be set to plastic, the material property of the connecting member 12 can be set to copper, and the corresponding elastic modulus and Poisson's ratio are set respectively according to the actual test requirements. Considering the incompressibility of the sealing member 13, the material property of the sealing member 13 can be set to rubber with a Shore A hardness of 70, and the Mooney-Rivlin material constitutive model is used for simulation, and the C10 and C01 parameters in the Mooney-Rivlin constitutive model are set. For example, the C10 parameter is set to 0.736, and the C01 parameter is set to 0.184. Among them, the material properties of the fixing member 11, the sealing member 13, and the connecting member 12 can all be set based on the actual situation of the component 1 to be measured, and are not limited here.

[0066] Step S203, fix the connecting member to the fixing member, and set the sealing member in the groove so that the sealing member contacts the bottom surface and the side surface of the groove to obtain the three-dimensional model of the component to be measured.

[0067] The connecting member 12 and the fixing member 11 are set to have common nodes, or the connecting member 12 and the fixing member 11 are set to be in bonded contact to fix the connecting member 12 to the fixing member 11. The sealing member 13 is set in the groove 110 so that the bottom surface of the sealing member 13 contacts the bottom surface of the groove 110 and the side surface of the sealing member 13 contacts the side surface of the groove 110. Through the above settings, a three-dimensional model corresponding to the component 1 to be measured is obtained.

[0068] In the process of constructing the three-dimensional model of the component 1 to be measured in this application, the connecting member 12 is fixed to the fixing member 11, and the sealing member 13 is set in the groove 110, so that the influence of the sealing member 13 on the deformation of the groove 110 can be considered during the simulation test, thereby improving the accuracy of the simulation test.

[0069] Please refer to Figure 6 , Figure 6 which Figure 2 is a schematic flowchart of an embodiment of step S102 in

[0070] Step S301: Constrain the degrees of freedom of the fixing member and the second segment.

[0071] Constrain the degrees of freedom of the fixing member 11 and the second segment 122. After constraining the degrees of freedom of the fixing member 11 and the second segment 122, displacements are respectively applied to the sealing member 13 and the connecting member 12 to generate the displacement values of the groove 110. Among them, the displacement values of the groove 110 include a first displacement value, a second displacement value, and a third displacement value.

[0072] Step S302: Apply a displacement to the upper surface of the sealing member along a first direction, so that the fixing member moves a first preset value along the first direction, and generate a first displacement value of the groove along the first direction.

[0073] Apply a displacement to the upper surface of the sealing member 13 along the first direction Z1, so that the fixing member 11 moves a first preset value along the first direction Z1. Among them, the upper surface of the sealing member 13 is the side of the sealing member 13 away from the groove 110. The first direction Z1 is perpendicular to the sealing surface 111, that is, the first direction Z1 is parallel to the Z axis. The first preset value can be the difference between the height of the sealing member 13 and the depth of the groove 110. When the fixing member 11 moves a first preset value along the first direction Z1, due to the constraints on the degrees of freedom of the fixing member 11 and the second segment 122, the displacement value of the groove 110 moving along the first direction Z1, that is, the first displacement value, may be different from the first preset value. By submitting a solution in the Abaqus environment, the first displacement value of the groove 110 along the first direction Z1 can be generated. The first displacement value is used to represent the deformation degree of the groove 110 along the first direction Z1 under the condition of not considering the installation tolerance of the connecting member 12.

[0074] Step S303: Apply a displacement to the upper surface of the sealing member along the first direction, so that the fixing member moves a first preset value along the first direction, and apply a displacement to the first segment along a second direction, so that the first segment moves a second preset value along the second direction, and generate a second displacement value of the groove along the first direction.

[0075] Apply displacement to the upper surface of the seal 13 along the first direction Z1 to move the fixing member 11 along the first direction Z1 by a first preset value, and apply displacement to the first section 121 along the second direction Y1 to move the first section 121 along the second direction Y1 by a second preset value. Wherein, the second direction Y1 is perpendicularly directed to the surface of the first section 121, that is, the second direction Y1 is parallel to the Y-axis. The second preset value can be calculated according to the dimensional chain of the component 1 to be measured. When the fixing member 11 moves along the first direction Z1 by the first preset value and the first section 121 moves along the second direction Y1 by the second preset value, by submitting a solution in the Abaqus environment, a second displacement value of the groove 110 along the first direction Z1 can be generated. The second displacement value is used to represent the deformation degree of the groove 110 along the first direction Z1 under a working condition considering the installation tolerance of the connecting member 12.

[0076] Step S304, apply displacement to the upper surface of the seal along the first direction to move the fixing member along the first direction by a first preset value, and apply displacement to the first section along the third direction to move the first section along the third direction by a third preset value, generating a third displacement value of the groove along the first direction.

[0077] Apply displacement to the upper surface of the seal 13 along the first direction Z1 to move the fixing member 11 along the first direction Z1 by a first preset value, and apply displacement to the first section 121 along the third direction Y2 to move the first section 121 along the third direction Y2 by a third preset value. Wherein, the third direction Y2 is opposite to the second direction Y1, that is to say, the second direction Y1 and the third direction Y2 are two opposite directions on the Y-axis. The third preset value can be calculated according to the dimensional chain of the component 1 to be measured. When the fixing member 11 moves along the first direction Z1 by the first preset value and the first section 121 moves along the third direction Y2 by the third preset value, by submitting a solution in the Abaqus environment, a third displacement value of the groove 110 along the first direction Z1 can be generated. The third displacement value is used to represent the deformation degree of the groove 110 along the first direction Z1 under another working condition considering the installation tolerance of the connecting member 12.

[0078] After restricting the degrees of freedom of the fixing member 11 and the second section 122 in this application, displacements are respectively applied to the upper surface of the seal 13 or the upper surface of the seal 13 and the first section 121 under different working conditions to generate displacement values of the groove 110 along the first direction Z1 under different working conditions, so as to more accurately simulate the deformation degree of the groove 110 under different working conditions and improve the accuracy of the simulation test.

[0079] In some embodiments, the fixing member 11 is further provided with a plurality of fixing holes 113, and the second section 122 includes a second connection end 1221 away from the fixing member 11, and the second connection end 1221 is provided with a second mounting hole 1220. Wherein, both the fixing holes 113 and the second mounting holes 1220 can be simulated using rbe2 elements.

[0080] Step S301 includes: restricting the degrees of freedom of a plurality of fixing holes and the degrees of freedom of the second mounting hole.

[0081] Restrict the degrees of freedom of the plurality of fixing holes 113 of the fixing member 11 and restrict the degrees of freedom of the second mounting hole 1220.

[0082] In some embodiments, the fixing member 11 is provided with three fixing holes 113. The connecting member 12 includes three connecting members 12 arranged side by side and spaced apart from each other on the fixing member 11 in sequence, and each connecting member 12 is provided with a second mounting hole 1220. Restrict the degrees of freedom of the three fixing holes 113 and the degrees of freedom of the three second mounting holes 1220, and a total of six degrees of freedom of the three-dimensional model of the component 1 to be measured are restricted.

Among them, the first mounting hole 1210 can be simulated by an rbe2 element.

[0084] Applying a displacement to the first section 121 along the second direction Y1 in step S303 to make the first section 121 move a second preset value along the second direction Y1 includes: applying a displacement to the first connection end 1211 along the second direction Y1 to make the center of the first mounting hole 1210 move a second preset value along the second direction Y1. Among them, the second preset value can be calculated by accumulating the dimensional tolerances on the dimensional chain of the component 1 to be measured to the first mounting hole 1210. The second displacement value is used to represent the deformation degree of the groove 110 along the first direction Z1 under a working condition considering the mating limit tolerance of the first mounting hole 1210 of the connecting member 12. It can be understood that the second preset value is related to the dimensions of each component of the component 1 to be measured and the assembly situation of the components. In some embodiments, the second preset value can be 1 mm.

[0085] Applying a displacement to the first section 121 along the third direction Y2 in step S304 to make the first section 121 move a third preset value along the third direction Y2 includes: applying a displacement to the first connection end 1211 along the third direction Y2 to make the center of the first mounting hole 1210 move a third preset value along the third direction Y2. Among them, the third preset value can be calculated by accumulating the dimensional tolerances on the dimensional chain of the component 1 to be measured to the first mounting hole 1210. The third displacement value is used to represent the deformation degree of the groove 110 along the first direction Z1 under another working condition considering the mating limit tolerance of the first mounting hole 1210 of the connecting member 12. It can be understood that the third preset value is related to the dimensions of each component of the component 1 to be measured and the assembly situation of the components. In some embodiments, the third preset value can be 1 mm, or the third preset value is the same as the second preset value.

[0086] Please refer to Figure 7 and Figures 8A - 8C , Figure 7 which is Figure 2 a schematic flow chart of another embodiment of step S102 in Figure 8A and Figure 7 is the displacement nephogram of a fixing member and a second segment in one embodiment of Figure 8B and Figure 7 is the displacement nephogram of a fixing member and a second segment in another embodiment of Figure 8C and Figure 7 is the displacement nephogram of a fixing member and a second segment in yet another embodiment of. Step S102 further includes the following steps.

[0087] Step S401: Apply displacements to the 3D model of the component to be measured to generate the test displacement values of each part of the groove along the first direction.

[0088] Based on different pre-set working conditions, apply different displacements to the 3D model of the component 1 to be measured to generate the test displacement values of each part of the groove 110 along the first direction Z1. Submitting for solution in the Abaqus environment can generate a displacement nephogram as shown in Figures 8A - 8C . Figure 8A is the displacement nephogram of the fixing member 11 and the second segment 122 when, under the working condition of not considering the installation tolerance of the connecting member 12, i.e., applying a displacement to the upper surface of the seal 13 along the first direction Z1 to move the fixing member 11 along the first direction Z1 by a first preset value. Figure 8B is the displacement nephogram of the fixing member 11 and the second segment 122 when, under one working condition considering the mating limit tolerance of the first mounting hole 1210 of the connecting member 12, i.e., applying a displacement to the upper surface of the seal 13 along the first direction Z1 to move the fixing member 11 along the first direction Z1 by a first preset value and applying a displacement to the first connection end 1211 along the second direction Y1 to move the center of the first mounting hole 1210 along the second direction Y1 by a second preset value. Figure 8C is the displacement nephogram of the fixing member 11 and the second segment 122 when, under another working condition considering the mating limit tolerance of the first mounting hole 1210 of the connecting member 12, i.e., applying a displacement to the upper surface of the seal 13 along the first direction Z1 to move the fixing member 11 along the first direction Z1 by a first preset value and applying a displacement to the first connection end 1211 along the third direction Y2 to move the center of the first mounting hole 1210 along the third direction Y2 by a third preset value. Among them, the displacement nephogram is used to represent the distribution of the displacements generated by the fixing member 11 and the second segment 122 along the first direction Z1. It can be understood that the displacement nephogram includes the distribution of the displacements generated by each part of the groove 110 along the first direction Z1, that is, the test displacement values.

[0089] Step S402: Select the maximum test displacement value among the test displacement values of all parts as the displacement value of the groove.

[0090] Under each working condition, select the maximum test displacement value among the test displacement values of all parts of the groove 110 as the displacement value of the groove 110. For example, the maximum test displacement value of the groove 110 selected under the working condition without considering the installation tolerance of the connecting member 12 is the first displacement value; the maximum test displacement value of the groove 110 selected under a working condition considering the limit tolerance of the first mounting hole 1210 of the connecting member 12 is the second displacement value; the maximum test displacement value of the groove 110 selected under another working condition considering the limit tolerance of the first mounting hole 1210 of the connecting member 12 is the third displacement value.

[0091] In some embodiments, select the maximum test displacement value of the groove 110 in each displacement nephogram as the displacement value of the groove 110. For example, Figure 8A in the displacement nephogram shown, if the maximum test displacement value among all parts of the groove 110 is 0.05 mm, then the first displacement value is 0.05 mm; Figure 8B in the displacement nephogram shown, if the maximum test displacement value among all parts of the groove 110 is 0.06 mm, then the second displacement value is 0.06 mm; Figure 8C in the displacement nephogram shown, if the maximum test displacement value among all parts of the groove 110 is 0.08 mm, then the third displacement value is 0.05 mm.

[0092] In this application, by taking the maximum test displacement value among all parts of the groove 110 as the displacement value of the groove 110, the part where the deformation of the groove 110 is the most serious can be considered, thereby improving the accuracy of judging the sealing performance of the component 1 to be tested.

[0093] Please refer to Figure 9 , Figure 9 which Figure 2 is a schematic flow chart of an embodiment of step S103 in

[0094] Step S501: Calculate the compression ratio based on the displacement value, the depth of the groove, and the height of the seal.

[0095] Calculate the first compression ratio based on the first displacement value, the depth of the groove 110, and the height of the seal 13, calculate the second compression ratio based on the second displacement value, the depth of the groove 110, and the height of the seal 13, and calculate the third compression ratio based on the third displacement value, the depth of the groove 110, and the height of the seal 13.

[0096] Step S502: Determine the sealing performance of the component to be tested based on the compression ratio and the preset condition value.

[0097] Determine whether the compression ratio is greater than a preset condition value. When the compression ratio is greater than the preset condition value, it indicates that the sealing performance of the component 1 to be tested is reliable; when the compression ratio is less than or equal to the preset condition value, it indicates that the sealing performance of the component 1 to be tested is unreliable. Respectively determine whether the first compression ratio is greater than the preset condition value, whether the second compression ratio is greater than the preset condition value, and whether the third compression ratio is greater than the preset condition value. In some embodiments, when the first compression ratio, the second compression ratio, and the third compression ratio are all greater than the preset condition value, it indicates that the sealing performance of the component 1 to be tested is reliable. Or, when at least two of the first compression ratio, the second compression ratio, and the third compression ratio are greater than the preset condition value, it indicates that the sealing performance of the component 1 to be tested is reliable. Among them, the preset condition value can be set according to the actual simulation test situation. For example, the preset condition value can be set to 18%, which is not limited here.

[0098] In some embodiments, step S501 includes: calculating a first difference between the height of the seal 13 and the depth of the groove 110; calculating a second difference between the first difference and the displacement value; calculating the percentage between the second difference and the height of the seal 13 to obtain the compression ratio. The height of the seal 13 is the height of the seal 13 before applying displacement to the upper surface of the seal 13, that is to say, the height of the seal 13 is the original height of the seal 13 before deformation occurs. The process of calculating the compression ratio can be expressed by the formula: K = [(h0 - h1 - s) / h0] * 100%. Wherein, K represents the compression ratio, h0 represents the height of the seal 13, h1 represents the depth of the groove 110, and s represents the displacement value.

[0099] In some embodiments, a second difference between the first difference and the first displacement value is calculated, and a percentage between the second difference and the height of the seal 13 is calculated to obtain the first compression rate; a second difference between the first difference and the second displacement value is calculated, and a percentage between the second difference and the height of the seal 13 is calculated to obtain the second compression rate; a second difference between the first difference and the third displacement value is calculated, and a percentage between the second difference and the height of the seal 13 is calculated to obtain the third compression rate. For example, when the height of the seal 13 is 4.15 mm and the depth of the groove 110 is 3 mm, the first preset value is 1.15 mm. When the first displacement value is 0.05 mm, the first compression rate is [(4.15 mm - 3 mm - 0.05 mm) / 4.15 mm] * 100% = 26.5%; when the second displacement value is 0.06 mm, the second compression rate is [(4.15 mm - 3 mm - 0.06 mm) / 4.15 mm] * 100% = 26.3%; when the third displacement value is 0.08 mm, the third compression rate is [(4.15 mm - 3 mm - 0.08 mm) / 4.15 mm] * 100% = 25.8%. In this case, the first compression rate of 26.5% is greater than the preset condition value of 18%, the second compression rate of 26.3% is greater than the preset condition value of 18%, and the third compression rate of 25.8% is greater than the preset condition value of 18%, so the sealing performance of the component 1 to be tested is reliable.
