Description

Technical Field

[0001] The present application relates to the field of simulation test technology, and in particular to a tire simulation sample acquisition method, device, electronic device and storage medium. Background Art

[0002] As the only part of a vehicle that contacts the road, tires affect the mechanical and safety performance of the entire vehicle. At present, the mechanical performance test of tires is mainly carried out through bench tests, trailers and virtual tests. Because bench tests and trailer tests have a long test cycle and high costs, the current automotive and tire industries are paying more and more attention to the virtual test technology of tires, that is, obtaining the mechanical properties of tires through virtual tests.

[0003] In the related art, finite element modeling is usually performed on the design profile of a tire provided by a tire company to obtain a simulation model of the tire, and a mechanical property test is performed on the tire simulation model to obtain a virtual test result of the tire.

[0004] However, the design profile of the tire provided by the tire company is the profile that the tire company refers to when manufacturing the tire. During the tire manufacturing process, the actual profile of the tire is not necessarily the same as the design profile. Directly using the simulation model corresponding to the design profile as the simulation model of the tire for mechanical performance testing may result in virtual test results that are inconsistent with the actual mechanical properties of the tire, affecting the mechanical properties analysis of the entire vehicle.

[0005] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Summary of the invention

[0006] In view of this, the present application provides a tire simulation sample acquisition method, device, electronic device and storage medium, so as to solve the problem in the prior art that the design profile of the tire provided by the tire company is the profile that the tire company refers to when manufacturing the tire. During the tire manufacturing process, the actual profile of the tire is not necessarily the same as the design profile. Directly using the simulation model corresponding to the design profile as the simulation model of the tire for mechanical performance testing may result in the virtual test results being inconsistent with the actual mechanical properties of the tire, thereby affecting the mechanical properties analysis of the entire vehicle.

[0007] In a first aspect, an embodiment of the present application provides a method for obtaining a tire simulation sample, comprising:

[0008] Acquire a first tire model and a second tire model corresponding to the tire, wherein the first tire model is a model obtained by scanning the tire, and the second tire model is a model corresponding to a design profile corresponding to the tire;

[0009] Obtaining a first similarity corresponding to the first tire model and a second similarity corresponding to the second tire model, wherein the first similarity is a similarity between a test result of the first tire model and an actual test result corresponding to the tire, and the second similarity is a similarity between a test result of the second tire model and the actual test result;

[0010] The tire model corresponding to the higher similarity between the first similarity and the second similarity is used as a tire simulation sample.

[0011] In the embodiment of the present application, a first tire model and a second tire model corresponding to the tire are obtained, the first tire model is a model generated by scanning the actual tire, and the second tire model is a model corresponding to the design profile of the tire. The two models are simulated and tested, and the two simulation results are compared with the actual test results of the tire, and the tire model with higher similarity is used as a tire simulation sample. It can be understood that the actual tire is scanned and modeled to obtain the first tire model, and a more accurate tire simulation sample is obtained by reverse analysis of the finite element simulation method. The tire simulation sample is a sample used for virtual testing, and accurate virtual test results are obtained through accurate tire simulation samples.

[0012] In a possible implementation manner, the step of obtaining a first tire model corresponding to the tire includes:

[0013] Scanning a cross section of the tire to obtain an actual profile of the tire, wherein the actual profile includes material distribution of the tire;

[0014] Finite element simulation is performed on the actual contour image to obtain a first tire model corresponding to the tire.

[0015] In the embodiment of the present application, when obtaining the first tire model, the cross section of the tire is first scanned to obtain an actual tire profile, which includes the material distribution of the tire. The first tire model can be obtained by performing finite element simulation on the actual tire profile. It can be understood that scanning the cross section of the tire can not only obtain the inner and outer contours of the tire, but also obtain the material distribution in the tire, which is conducive to improving the simulation accuracy.

[0016] In a possible implementation manner, the step of obtaining a second tire model corresponding to the tire includes:

[0017] Finite element simulation is performed on the design contour drawing corresponding to the tire to obtain a second tire model corresponding to the tire.

[0018] In the embodiment of the present application, the second tire model is obtained by performing finite element simulation on the design contour diagram corresponding to the tire, so as to obtain an accurate second tire model for subsequent simulation testing.

[0019] In a possible implementation, the finite element simulation includes:

[0020] The tire and rim are installed in the implicit solver, and the inflation pressure of a preset pressure is input.

[0021] In the embodiment of the present application, because the tire is installed on the rim on the two-dimensional model and then a 3D model is generated by rotation, some specific functions can be achieved by installing the tire and the rim through the implicit solver, and the implicit solver has a faster simulation speed, which is conducive to improving work efficiency.

[0022] In a possible implementation manner, obtaining the first similarity and the second similarity includes:

[0023] Performing a simulation test on the first tire model to obtain a first simulation test result;

[0024] performing a simulation test on the second tire model to obtain a second simulation test result;

[0025] Obtaining actual test results of the tire;

[0026] Comparing the first simulation test result and the actual test result to obtain a first similarity;

[0027] The second simulation test result and the actual test result are compared to obtain a second similarity.

[0028] In the embodiment of the present application, the first tire model and the second tire model are simulated respectively to obtain the first simulation test result and the second simulation test result, and the first simulation test result and the second simulation test result are compared with the actual test result respectively to obtain the tire model corresponding to the simulation test result with higher similarity as the tire simulation sample. It can be understood that by using the tire model with higher similarity to the actual test result as the tire simulation sample, a more accurate tire simulation sample can be obtained, thereby improving the accuracy of the virtual test.

[0029] In a possible implementation, the simulation test includes:

[0030] The tires were tested for radial stiffness, lateral stiffness, longitudinal stiffness and torsional stiffness.

[0031] It is understood that the mechanical properties of a tire include radial stiffness, lateral stiffness, longitudinal stiffness and torsional stiffness. The embodiments of the present application test a variety of mechanical properties, which can make the test results more authoritative and accurate.

[0032] In a possible implementation, taking the tire model corresponding to the higher similarity between the first similarity and the second similarity as the tire simulation sample includes:

[0033] If the first similarity is greater than the second similarity, taking the first tire model as a tire simulation sample;

[0034] If the first similarity is less than the second similarity, taking the second tire model as a tire simulation sample;

[0035] If the first similarity is equal to the second similarity, the second tire model is used as a tire simulation sample.

[0036] In the embodiment of the present application, if the first similarity is equal to the second similarity, the second tire model is used as the tire simulation sample. It can be understood that when the first similarity is equal to the second similarity, directly using only the design profile of the tire to model and generate the tire simulation sample can increase the speed of obtaining the tire simulation sample.

[0037] In a second aspect, an embodiment of the present application provides a tire simulation sample acquisition device, comprising:

[0038] A tire model acquisition module, used to acquire a first tire model and a second tire model corresponding to the tire, wherein the first tire model is a model obtained by scanning the tire, and the second tire model is a model corresponding to a design profile corresponding to the tire;

[0039] a similarity acquisition module, configured to obtain a first similarity and a second similarity, wherein the first similarity is a similarity between a test result of the first tire model and an actual test result corresponding to the tire, and the second similarity is a similarity between a test result of the second tire model and the actual test result;

[0040] The tire simulation sample acquisition module is used to use the tire model corresponding to the higher similarity between the first similarity and the second similarity as the tire simulation sample.

[0041] In a third aspect, an embodiment of the present application provides an electronic device, including:

[0042] processor;

[0043] Memory;

[0044] A communication unit, used for establishing a communication channel;

[0045] And a computer program, wherein the computer program is stored in the memory, and the computer program includes instructions, and when the instructions are executed by the processor, the electronic device executes any one of the methods described in the first aspect.

[0047] It is understandable that the tire simulation sample acquisition device provided in the second aspect, the electronic device provided in the third aspect, and the computer-readable storage medium provided in the fourth aspect are used to execute the method provided in the present application. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding method, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0063] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0064] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0065] As the only part of a vehicle that contacts the road, tires affect the mechanical and safety performance of the entire vehicle. At present, the mechanical performance test of tires is mainly carried out through bench tests, trailers and virtual tests. Because bench tests and trailer tests have a long test cycle and high costs, the current automotive and tire industries are paying more and more attention to the virtual test technology of tires, that is, obtaining the mechanical properties of tires through virtual tests.

[0066] In the related art, finite element modeling is usually performed on the design profile of a tire provided by a tire company to obtain a simulation model of the tire, and a mechanical property test is performed on the tire simulation model to obtain a virtual test result of the tire.

[0067] However, the design profile of the tire provided by the tire company is the profile that the tire company refers to when manufacturing the tire. During the tire manufacturing process, the actual profile of the tire is not necessarily the same as the design profile. Directly using the simulation model corresponding to the design profile as the simulation model of the tire for mechanical performance testing may result in virtual test results that are inconsistent with the actual mechanical properties of the tire, affecting the mechanical properties analysis of the entire vehicle.

[0068] In response to the above problems, an embodiment of the present application provides a method for obtaining a tire simulation sample, by performing simulation tests on two models, and comparing the two simulation results with the actual test results of the tire, and taking the tire model with higher similarity as the tire simulation sample. It can be understood that the actual tire is scanned and modeled to obtain a first tire model, and a more accurate tire simulation sample is obtained by reverse analysis of the finite element simulation method. The tire simulation sample is a sample used for virtual testing, and accurate virtual test results are obtained through accurate tire simulation samples. This is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0069] See also Figure 1 , is a flow chart of a tire simulation sample acquisition method provided in an embodiment of the present application. Figure 1 As shown, it mainly includes the following steps.

[0070] Step S101: Acquire a first tire model and a second tire model corresponding to the tire.

[0071] Specifically, the tire simulation sample acquisition device scans the cross section of the tire to obtain an actual profile of the tire, the actual profile includes the material distribution of the tire, and performs finite element simulation on the actual profile to obtain a first tire model corresponding to the tire. In addition, by performing finite element simulation on the design profile corresponding to the tire, a second tire model corresponding to the tire is obtained. In other words, the first tire model is a model obtained by scanning the tire, and the second tire model is a model corresponding to the design profile corresponding to the tire.

[0072] In a possible implementation, a scanned image of the tire is obtained through 3D scanning, and the 3D scanning result is cut to obtain a cross-sectional image of the tire, and the cross-sectional image is printed on paper to obtain a 1:1 tire cross-sectional inner and outer contour drawing. The user radially cuts the tire to obtain a tire block with a certain width (or thickness), and places the tire block on the inner and outer contour drawing. Because the 3D scanning accuracy is very high, this tire block can be well matched with the inner and outer contour drawing.

[0073] For ease of understanding, the embodiment of the present application also provides a schematic diagram of tire truncation.

[0074] See also Figure 2, is a schematic diagram of a tire cutoff structure provided in an embodiment of the present application. Figure 2 As shown, the area between the tire inner contour 201 and the tire outer contour 202 is the tire area. When obtaining tire blocks, the tire is first cut radially once, and then cut again at intervals of a preset width to obtain tire blocks 203 of a preset width.

[0075] It should be noted that the width of the tire block can be set to any width according to actual conditions, and the present embodiment of the application does not impose any specific limitation on this. Figure 2 It is a two-dimensional schematic diagram of a tire. In actual application, the tire is three-dimensional, so the tire block is a tire block with a certain width and length.

[0076] See also Figure 3 , is a schematic diagram of a placement method of a tire block provided in an embodiment of the present application. Figure 3 As shown in the figure, the cut tire block is placed on the printed inner and outer contour drawing so that the outline of the tire block matches the outline on the drawing. Because it is a tire cross section, it can be clearly seen Figure 3 The toe, sidewall, shoulder and tread of the tire.

[0077] After the tire fragment is obtained, the cross section of the tire fragment is scanned to obtain an actual contour map of the tire, and the actual contour map includes the material distribution of the tire.

[0078] Because the tire is round, and the tire fragment captured in the present application is only a part of the tire, the entire tire can be divided into multiple tire fragments, and using only one tire fragment may not be representative, so the embodiment of the present application captures multiple tire fragments, scans them separately, and integrates multiple scanning results to generate the final actual contour map.

[0079] In one possible implementation, the tire circumference is divided according to the center angle, every 10°, and several angles are selected from multiple angles for cutting to obtain multiple actual contour images. For ease of understanding, an embodiment of the present application also provides a schematic diagram of the actual contour image of the tire.

[0080] See also Figure 4 , is a schematic diagram of an actual profile image of a tire provided in an embodiment of the present application. Figure 4 As shown, in the embodiment of the present application, four angles are selected for scanning, namely 90°, 180°, 270° and 360°. The actual contour image corresponding to 90° is cyan, the actual contour image corresponding to 180° is green, the actual contour image corresponding to 270° is yellow, and the actual contour image corresponding to 360° is blue.

[0081] There are differences between the multiple actual contour images corresponding to the same tire, but the differences are not large. After integrating the multiple actual contour images into an actual contour map, the actual contour map is compared with the design contour map. The embodiment of the present application also provides a schematic diagram for comparing the actual contour and the design contour.

[0082] See also Figure 5 , is a schematic diagram of a comparison between an actual profile and a designed profile provided in an embodiment of the present application. Figure 5 As shown, the red color is the actual contour and the cyan color is the design contour. It is understandable that although the design contour is the image drawn by the tire manufacturer when manufacturing the tire, the actual contour corresponding to the tire actually produced does not completely match the design contour. Blindly using the design contour for finite element simulation may lead to low accuracy of the simulation results.

[0083] After obtaining the actual contour map and the design contour map of the tire, finite element simulation is performed on the actual contour map and the design contour map respectively through professional finite element modeling software to obtain a first tire model corresponding to the actual contour map and a second tire model corresponding to the design contour map.

[0084] See also Figure 6 , is a structural schematic diagram of a two-dimensional tire model provided in an embodiment of the present application. Figure 6 Figure a is a schematic diagram of a 2D tire model with a rim installed. The left side is the 2D tire model corresponding to the design profile, and the right side is the 2D tire model corresponding to the actual profile. After obtaining the 2D finite element model of the tire, the cord material parameters and the rubber constitutive model are input to complete the construction of the finite element model, and the installation of the tire and rim is completed in the implicit solver. Figure 6 The red line in a in the figure is the wheel rim, and the thick black line is the tire carcass steel wire. After obtaining the two-dimensional tire model corresponding to the tire, the tire model is loaded with the preset inflation pressure in the implicit solver. Figure 6 As shown in b, it is a tire model loaded with an inflation pressure of a preset pressure. The left side is a two-dimensional tire model corresponding to the design profile, and the right side is a two-dimensional tire model corresponding to the actual profile. The closer the color is to red, the greater the pressure. In the embodiment of the present application, the preset pressure is 0.29MPa. Those skilled in the art can set the preset pressure to any value according to actual needs, and the embodiment of the present application does not make specific restrictions on this.

[0085] After obtaining the two-dimensional tire model corresponding to the tire, a first tire model corresponding to the design profile and a second tire model corresponding to the actual profile are generated by the rotational symmetry command. It can be understood that the first tire model and the second tire model are both three-dimensional models. The number of grids in the circumferential direction of the two three-dimensional models is 60, and the spacing between adjacent grids is 6°, where the circumferential direction is the rolling direction of the tire. For ease of understanding, the present embodiment provides a structural schematic diagram of a three-dimensional tire model.

[0086] See also Figure 7 , is a schematic diagram of the structure of a three-dimensional tire model provided in an embodiment of the present application. Figure 7 As shown in FIG. 1 , the tire model is a three-dimensional model, and the three-dimensional model is equipped with a rim and a preset inflation pressure. The number of grids in the circumferential direction of the three-dimensional tire model is 60, and the spacing between adjacent grids is 6°. Figure 7 The direction indicated by the arrow in the middle is, of course, only an exemplary description, and the reverse direction of the arrow direction is also the tire circumferential direction.

[0087] In summary, the tire is simulated by finite element method through reverse analysis to obtain the first tire model corresponding to the tire, and the design profile corresponding to the tire is simulated by finite element method to obtain the second tire model corresponding to the tire, so as to facilitate subsequent mechanical testing.

[0088] Step S102: obtaining a first similarity corresponding to the first tire model and a second similarity corresponding to the second tire model.

[0089] Specifically, a simulation test is performed on the first tire model to obtain a first simulation test result; a simulation test is performed on the second tire model to obtain a second simulation test result; an actual test result of the tire is obtained; the first simulation test result and the actual test result are compared to obtain a first similarity; the second simulation test result and the actual test result are compared to obtain a second similarity. In other words, the first similarity is the similarity between the test result of the first tire model and the actual test result corresponding to the tire, and the second similarity is the similarity between the test result of the second tire model and the actual test result.

[0090] In the embodiment of the present application, the simulation test includes testing the radial stiffness, lateral stiffness, longitudinal stiffness and torsional stiffness of the tire. For ease of understanding, the embodiment of the present application also provides a schematic diagram of a coordinate system corresponding to the tire.

[0091] See also Figure 8 , is a schematic diagram of a coordinate system corresponding to a tire provided in an embodiment of the present application. Figure 8As shown, the middle circle is the tire, and the horizontal plane below the tire is the simulated ground. When testing the radial stiffness of the tire / tire model, the simulated ground below the tire / tire model can be moved to cause the tire / tire model to generate radial displacement, and the radial load corresponding to different radial displacements can be tested. When testing the lateral stiffness of the tire / tire model, a lateral displacement is applied to the tire / tire model to test the lateral force corresponding to different lateral displacements. When testing the longitudinal stiffness of the tire / tire model, a longitudinal displacement is applied to the tire / tire model to test the longitudinal force corresponding to different longitudinal displacements. When testing the rotational stiffness of the tire / tire model, a steering angle is applied to the tire / tire model to test the return torque corresponding to different steering angles.

[0092] See also Fig. 9 , is a schematic diagram of a tire simulation test result provided in an embodiment of the present application. Fig. 9 a in the figure is a schematic diagram of the radial stiffness test results of the tire and tire model. Fig. 9 b is a schematic diagram of the lateral stiffness test results of the tire and tire model. Fig. 9 c in the figure is a schematic diagram of the longitudinal stiffness test results of the tire and tire model. Fig. 9 d in FIG. 4 is a schematic diagram of the torsional stiffness test results of the tire and the tire model. The “test” curve corresponds to the actual test result of the tire, the “design profile” curve corresponds to the test result of the second tire model, and the “actual profile” curve corresponds to the test result of the first tire model.

[0093] In one possible implementation, after the radial stiffness, lateral stiffness, longitudinal stiffness and torsional stiffness of the tire and tire model are tested, the radial stiffness, lateral stiffness, longitudinal stiffness and torsional stiffness of the first tire model and the second tire model at different inflation pressures can also be tested.

[0094] For ease of understanding, the embodiment of the present application also provides another schematic diagram of tire simulation test results.

[0095] See also Fig.10 , is another schematic diagram of tire simulation test results provided in an embodiment of the present application. Fig.10 a in the figure is a schematic diagram of the radial stiffness test results of the tire model corresponding to different inflation pressures. Fig.10 Figure b is a schematic diagram of the lateral stiffness test results of the tire model corresponding to different inflation pressures. Fig.10 c is a schematic diagram of the longitudinal stiffness test results of the tire model corresponding to different inflation pressures. Fig.10 d in FIG. 1 is a schematic diagram of the torsional stiffness test results of the tire model corresponding to different inflation pressures.

[0096] like Fig.10As shown, when the radial displacement is the same, the radial load corresponding to the first tire model and the second tire model is quite different, when the lateral displacement is the same, the lateral force corresponding to the first tire model and the second tire model is slightly different, when the longitudinal displacement is the same, the longitudinal force corresponding to the first tire model and the second tire model is slightly different, and when the torsion angle is the same, the self-aligning torque corresponding to the first tire model and the second tire model is slightly different.

[0097] After the first similarity and the second similarity are obtained, a tire simulation sample is determined according to the first similarity and the second similarity.

[0098] Step S103: taking the tire model corresponding to the higher similarity between the first similarity and the second similarity as a tire simulation sample.

[0099] Specifically, if the first similarity is greater than the second similarity, the first tire model is used as the tire simulation sample; if the first similarity is less than the second similarity, the second tire model is used as the tire simulation sample; if the first similarity is equal to the second similarity, the second tire model is used as the tire simulation sample.

[0100] It can be understood that when the first similarity is equal to the second similarity, directly using only the design profile of the tire to model and generate the tire simulation sample can increase the speed of obtaining the tire simulation sample.

[0101] Corresponding to the above-mentioned embodiment, the present application also provides a tire simulation sample acquisition device.

[0102] See also Fig.11 , is a tire simulation sample acquisition device provided in an embodiment of the present application. Fig.11 As shown, the tire simulation sample acquisition device may include: a tire model acquisition module 1101, a similarity acquisition module 1102, and a tire simulation sample acquisition module 1103.

It can be a bus structure or a star structure, and can also include more or fewer components than shown in the figure, or combine certain components, or arrange components differently.

[0103] The tire model acquisition module 1101 is used to acquire a first tire model and a second tire model corresponding to the tire, wherein the first tire model is a model obtained by scanning the tire, and the second tire model is a model corresponding to a design profile corresponding to the tire;

[0105] The tire simulation sample acquisition module 1103 is configured to use the tire model corresponding to the higher similarity between the first similarity and the second similarity as a tire simulation sample.

[0106] Corresponding to the above embodiments, the present application also provides an electronic device.

[0107] See also Fig.12 , is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. Fig.12 As shown, the electronic device 1200 may include: a processor 1201, a memory 1202 and a communication unit 1203. These components communicate via one or more buses. Those skilled in the art will appreciate that the structure of the electronic device shown in the figure does not limit the embodiments of the present application. It may be a bus structure or a star structure, and may include more or fewer components than shown in the figure, or combine certain components, or arrange components differently.

[0108] The communication unit 1203 is used to establish a communication channel so that the electronic device can communicate with other devices, receive user data sent by other devices or send user data to other devices.

[0109] The processor 1201 is the control center of the electronic device. It uses various interfaces and lines to connect various parts of the entire electronic device. It runs or executes software programs, instructions, and / or modules stored in the memory 1202, and calls data stored in the memory to perform various functions of the electronic device and / or process data.
