[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] Embodiment one

[0037] Please refer to Figure 1 is a flowchart of a vehicle part simulation modeling method provided by an embodiment of the present application. The vehicle part simulation modeling method specifically includes the following steps.

[0038] S1: intercepting a part picture under different visual angles from a pre-constructed vehicle simulation model;

[0039] For the visual angle of the intercepted part picture, a plurality of optimal different visual angles are selected according to the characteristics of different automobile assembly parts to take screenshots, so as to improve the recognizability of the part picture.

[0040] Further, the part picture carries a size identifier of a corresponding part to be modeled. The size identifier carried by the part picture is used to keep the coordinates of the part to be modeled consistent with the coordinates of the part to be modeled in the vehicle simulation model.

[0041] S2: identifying key features of the part to be modeled according to the part picture under different visual angles, and obtaining two-dimensional plane coordinates of the key features;

[0042] For the intercepted part picture, the part picture is imported into an image recognition program to distinguish automobile assembly parts and identify key features of each automobile assembly part to be modeled. Since engineers do not need to identify one by one, the range of automatically identifiable features can be effectively expanded, and errors caused by non-standard initial data in the automobile design stage can be distinguished to improve modeling accuracy.

[0043] S3: converting the two-dimensional plane coordinates of the key features into three-dimensional coordinates;

[0044] S4: modeling the part to be modeled in the vehicle simulation model according to the three-dimensional coordinates.

[0045] In the embodiment of the present application, based on the three-dimensional coordinates of the identified key features, modeling of the parts to be modeled is performed in the vehicle simulation model, and the entire modeling process does not require engineers to identify and model the parts to be modeled one by one, effectively reducing the dependence on the knowledge of engineers in the modeling process, standardizing the pre-modeling process, effectively improving the automation of vehicle part modeling, and shortening the time required for modeling.

[0046] In an alternative embodiment, the part pictures under different perspectives are intercepted from the pre-constructed vehicle simulation model, including:

[0047] The vehicle simulation model is imported into the finite element pre-processing software, and the vehicle simulation model is photographed from different perspectives by the finite element pre-processing software to obtain part pictures under different perspectives.

[0048] Further, the vehicle simulation model is photographed from the perspectives corresponding to the X-axis, Y-axis and Z-axis of the reference coordinate system by the finite element pre-processing software to obtain part pictures under the X, Y and Z directions. The reference coordinate system is a three-dimensional rectangular coordinate system defined in advance in the finite element pre-processing software.

[0049] The finite element pre-processing software can be ansa, hyperwords or the like. The image recognition program can be independent of the finite element pre-processing software, only leaving an interface to connect with the finite element pre-processing software to reduce the difficulty of implementation of the present application, or the image recognition program is integrated into the finite element pre-processing software to become a part of the finite element pre-processing software, thereby improving the modeling efficiency.

[0050] In an alternative embodiment, the key features of the parts to be modeled are identified according to the part pictures under different perspectives, and two-dimensional plane coordinates of the key features are obtained, including:

[0051] The part pictures under all perspectives are subjected to image recognition by a pre-trained deep learning model to identify the key features of the parts to be modeled;

[0052] According to the position association relationship between the part pictures and the vehicle simulation model, two-dimensional plane coordinates of the key features on different planes are obtained.

[0053] Further, according to the position association relationship between the part pictures and the vehicle simulation model, two-dimensional plane coordinates of the key features on XY, YZ and ZX planes are obtained.

[0054] In an alternative embodiment, the three-dimensional coordinates are used to perform modeling of the parts to be modeled in the vehicle simulation model, including:

[0055] importing the three-dimensional coordinates into the finite element pre-processing software to identify model features in the vehicle simulation model according to the three-dimensional coordinates;

[0056] establishing a finite element model for the modeling part according to the identified model features.

[0057] In the embodiment of the application, the finite element pre-processing software identifies model features such as connected holes, connection sites, materials, etc. based on the three-dimensional coordinates, and performs operations such as creating connections, assigning materials, and establishing contacts on the identified model features, thereby realizing the modeling of the finite element model of the modeling part in the vehicle simulation model.

[0058] For example, as shown in the figure, the modeling process using the image recognition program combined with the finite element pre-processing software is as follows: Figure 2

[0059] 1. The finite element pre-processing software opens the basic mesh, and cuts the part picture to be identified from the X, Y, and Z directions; wherein the vehicle simulation model is imported into the finite element pre-processing software in advance.

[0060] 2. The part picture is passed to the image recognition program based on deep learning, and the key features of modeling are identified.

[0061] 3. Based on the positional correlation between the part picture and the vehicle simulation model, the two-dimensional plane coordinates of the identified key features on the XY, YZ, and ZX planes are extracted.

[0062] 4. The two-dimensional plane coordinates of the key features are converted into three-dimensional coordinates.

[0063] 5. The three-dimensional coordinates of the key features are transmitted back to the finite element pre-processing software.

[0064] 6. The finite element pre-processing software identifies model features based on the three-dimensional coordinates of the key features and automatically models.

[0065] After establishing the finite element model of the automobile part in the finite element pre-processing software, the finite element model can be subjected to automobile collision finite element simulation, and the corresponding real automobile parts can be subjected to real collision test. For automobile collision finite element simulation and real collision test, the various loads on the automobile are analyzed, the strength and stiffness of the automobile structure are calculated, and the above parameters are compared and analyzed, thereby obtaining the correctness of the finite element model. If the correctness is lower than the set threshold, the part picture recognition and modeling process are re-executed.

[0066] Compared with the prior art, the embodiment of the application has the following advantages:

[0067] ​1. The application can expand the range of automatically identifiable features by capturing part pictures from different perspectives and identifying key features of the part pictures from different perspectives. It can also distinguish errors caused by non-standard initial data in the automobile design stage, improving modeling accuracy.

[0068] 2. Based on the three-dimensional coordinates of the identified key features, modeling of the proposed modeling parts is performed in the vehicle simulation model. The entire modeling process does not require engineers to identify and model the proposed modeling parts one by one, effectively reducing the dependence on engineers' knowledge during the modeling process. It achieves standardization before modeling, effectively improves the automation level of vehicle part modeling, shortens the time-consuming of modeling, improves the standardization of analysis, and thus improves the simulation analysis capability.

[0069] 3. The combination of image recognition and finite element pre-processing can further expand the range of automatically identifiable features, improve the automation level of modeling, shorten the cycle of automobile development analysis, and improve product competitiveness.
