[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. The present application provides a method and device for analyzing the strength of automotive components, which are used in the field of automotive technology. The above is only an example and does not limit the application field of the method and device provided by the present application.
[0045] As an important part of the vehicle, automobile components bear the weight and torque of the vehicle. The strength analysis of vehicle components is an important indicator to ensure the safety, reliability and durability of the vehicle. In the prior art, in order to analyze the strength of each component in the vehicle, it is often necessary to produce the finished vehicle first, and then conduct bench tests on each component in the vehicle, which is equivalent to testing the actual vehicle, so as to obtain the strength of each automobile component and the strength of the vehicle. However, the development of the actual vehicle takes a lot of time, and the various components in the actual vehicle produced may not necessarily meet the requirements. Therefore, it is necessary to produce the actual vehicle twice or even multiple times until the various components in the vehicle meet the requirements. This method is inefficient and costly.
[0046] After research, the inventor proposed the technical solution of this application. First, the shape information and attribute information of the target component are obtained, and then the geometric model of the target component is constructed using the shape information. Then, the attribute information is imported into the geometric model to obtain the geometric model with various attributes of the target component. Finally, the description file of the model is output, and the description file is solved to obtain the strength information of the target component. In this way, before the development of the finished vehicle is completed, the strength analysis of each component of the vehicle can be completed by using only the geometric model of each component, which greatly increases the efficiency of the strength analysis of automobile components and reduces the cost of the strength analysis of automobile components.
[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0048] See also Figure 1 , Figure 1 A method flow chart of a method for analyzing the strength of an automobile component provided in an embodiment of the present application includes:
[0049] S101, obtaining relevant information of a target component.
[0050] Among them, the relevant information includes the appearance information and attribute information of the target element; the appearance information is information used to describe the shape of the target element, for example, the appearance information may include the length, width, height, etc. of the target element; the attribute information is information that can describe the physical properties of the target element, for example, the attribute information may include the material, working condition, load and other information of the target element; the target element is an automobile component that requires strength analysis, for example, the target element may be a welded part of the front axle of an automobile.
[0051] Specifically, when the developer is developing a vehicle, the appearance information and attribute information of each component in the vehicle will be set, and the appearance information and attribute information of each component in the vehicle will be uploaded to the storage system. When the target component needs to be analyzed for strength, the name of the target component is used as the search keyword to search and obtain the appearance information and attribute information corresponding to the target component in the storage system. That is, when the target component needs to be analyzed for strength, the appearance information and attribute information of the target component can be directly searched from the storage system, which greatly increases the efficiency and convenience of information acquisition.
[0052] S102, constructing a geometric model of the target component according to the shape information.
[0053] The geometric model is a three-dimensional spatial model that can describe the shape of the target component.
[0054] Specifically, a geometric model of the target element may be made in proportion according to information such as the length, width, height, thickness, and curvature of the target element in the shape information, so that the geometric model can fully display the shape of the target element.
[0055] For example, the target element may be directly scanned, and the scanning result may be used as a geometric model of the target element. There are many methods for constructing the geometric model, which are not limited here.
[0056] The geometric model of the target element constructed using this method can highly restore the target element, thereby increasing the accuracy of the results of subsequent strength analysis of the target element.
[0057] S103, importing the attribute information into the geometric model and outputting the description file of the target component.
[0058] The description file is a file that can fully describe the target component, including at least the appearance information and attribute information of the target component. For example, the description file can be an inp file.
[0059] Specifically, Hypermesh can be used to create the material properties, boundary conditions, and load conditions of the target component in the geometric model during actual vehicle use, so that the geometric model can truly simulate the actual situation during the use of the actual vehicle. At this time, the imported geometric model is exported as the target file. The description file obtained by this method can fully describe the situation of the target component in the actual vehicle, so that the geometric model of the target component can replicate the target component in the actual vehicle, greatly increasing the accuracy of the subsequent strength test of the target component.
[0060] S104, solving the description file to obtain strength information of the target element.
[0061] The strength information is information describing the strength of the target element.
[0062] Specifically, the abaqus solver can be used to solve the description file and directly obtain the strength information of the target component.
[0063] Optionally, a finite element analysis may be performed on the description file to obtain the maximum stress of the target element; and strength evaluation may be performed based on the maximum stress of the target element to obtain strength information of the target element.
[0064] The maximum stress is the maximum force that the target component can withstand.
[0065] For example, the abaqus solver can be used to perform finite element analysis on the description file and output the maximum stress of the target element. The maximum stress is compared with the preset stress-intensity relationship table to obtain the strength information of the target element.
[0066] In the above embodiment, the appearance information and attribute information of the target element are first obtained, and then the geometric model of the target element is constructed using the appearance information, and then the attribute information is imported into the geometric model to obtain the geometric model with various attributes of the target element, and finally the description file of the model is output, and the description file is solved to obtain the strength information of the target element. In this way, before the development of the finished vehicle is completed, the strength analysis of each component of the vehicle can be completed by using only the geometric model of each component, which greatly increases the efficiency of the strength analysis of the automobile components and reduces the cost of the strength analysis of the automobile components.
[0067] In the embodiment of the present application, the above Figure 1There are multiple possible implementations of steps S101-S104, which are described below. It should be noted that the implementations described below are only exemplary and do not represent all implementations of the embodiments of the present application.
[0068] See also Figure 2 ,This figure shows the specific process of importing attribute information into the geometric model and outputting the description file of the target component.
[0069] S201, dividing the geometric model grid into a plurality of analysis units.
[0070] The analysis unit is a part of the geometric model.
[0071] For example, the geometric model mesh can be divided into equilateral quadrilaterals with a size of 5 mm. There may be welded parts in the target component, and the thickness of the weld can be given to be 5 mm. Shell elements can be used to simulate the weld, so that the geometric model can be divided into multiple analysis units.
[0072] S202, importing the attribute information into each analysis unit, and outputting a description file of the target component.
[0073] Specifically, since the attribute information of each analysis unit may be different, the attribute information corresponding to each analysis unit is imported into each analysis unit respectively according to the attribute information corresponding to each analysis unit, so as to obtain a complete geometric model with attribute information. The geometric model is exported to obtain the description file of the target element.
[0074] Optionally, the attribute information includes material information and restriction information. The method of importing the attribute information into each analysis unit and outputting the description file of the target element can also be: importing the material information into each analysis unit to obtain the transition model of the target element; importing the restriction information into the transition model, and outputting the description file of the target element.
[0075] Among them, material information is information that describes the material of the target component. For example, the material of an automobile component is usually steel, and the material information can be defined as E=2.1E+05, NU=0.3, and RHO=7.83E-9. Limitation information is the physical limitations and load limitations of the automobile component. For example, a vehicle designed based on the target component must meet certain operating requirements.
[0076] Specifically, the thickness of the target component can be measured first, and then the properties of the steel (E=2.1E+05, NU=0.3, RHO=7.83E-9) can be associated with the target component; in addition, the restriction information that the entire vehicle needs to meet can be associated with the target component. For example, you can first create a load set named: force_case1; define the card type: HISTORY; and assign the force and moment of the connection hard point between the chassis and the target component under working condition 1; create a boundary condition load set and name it SPC, constrain the front axle weldment and the body connection point in 1-6 directions of freedom, and define the card type: INIYIAL_CONDITION; create OUTPUT BLOCK and name it output1, set the OUTPUT card, output the node displacement U, mesh stress S and other parameters; create an analysis step and name it Step-1, check the load set force_case1 defined by S1 and output1 defined by S4; set the analysis type to Static; turn on the nonlinear switch; set the analysis increment step to 0.1, and the association of one type of restriction information to the target element is completed. The association method of the remaining restriction information is similar to the above method and will not be repeated here.
[0077] In the above example, the geometric model is first divided into multiple analysis units, and then the material information is imported into each analysis unit to obtain a transition model. Finally, the restriction information is imported into the transition model, and the description file of the target component is output. Dividing the model into multiple analysis units and importing the material information separately can more accurately describe the material of the collective model. Importing the attribute information can enable the final geometric model to completely replicate the target component in the actual vehicle. The description file exported based on this geometric model can describe the target component more comprehensively and completely, so that the strength of the target component subsequently obtained based on this description file is more accurate.
[0078] The above introduces the automobile component strength analysis method provided in the embodiment of the present application. The following is an exemplary description of the automobile component strength analysis method in combination with a specific application scenario.
[0079] See also Figure 3 , provides a more comprehensive automotive component strength analysis method, which includes:
[0080] S301, obtaining relevant information of the target component.
[0081] Among them, the relevant information includes the appearance information and attribute information of the target element; the appearance information is information used to describe the shape of the target element, for example, the appearance information may include the length, width, height, etc. of the target element; the attribute information is information that can describe the physical properties of the target element, for example, the attribute information may include the material, working condition, load and other information of the target element; the target element is an automobile component that requires strength analysis, for example, the target element may be a welded part of the front axle of an automobile.
[0082] Specifically, when the developer is developing a vehicle, the appearance information and attribute information of each component in the vehicle will be set, and the appearance information and attribute information of each component in the vehicle will be uploaded to the storage system. When the target component needs to be analyzed for strength, the name of the target component is used as the search keyword to search and obtain the appearance information and attribute information corresponding to the target component in the storage system. That is, when the target component needs to be analyzed for strength, the appearance information and attribute information of the target component can be directly searched from the storage system, which greatly increases the efficiency and convenience of information acquisition.
[0083] S302: construct a geometric model of the target component according to the shape information.
[0084] The geometric model is a three-dimensional spatial model that can describe the shape of the target component.
[0085] Specifically, a geometric model of the target element may be made in proportion according to information such as the length, width, height, thickness, and curvature of the target element in the shape information, so that the geometric model can fully display the shape of the target element.
[0086] For example, the target element may be directly scanned, and the scanning result may be used as a geometric model of the target element. There are many methods for constructing the geometric model, which are not limited here.
[0087] The geometric model of the target element constructed using this method can highly restore the target element, thereby increasing the accuracy of the results of subsequent strength analysis of the target element.
[0088] S303, dividing the geometric model grid into a plurality of analysis units.
[0089] The analysis unit is a part of the geometric model.
[0090] For example, the geometric model mesh can be divided into equilateral quadrilaterals with a size of 5 mm. There may be welded parts in the target component, and the thickness of the weld can be given to be 5 mm. Shell elements can be used to simulate the weld, so that the geometric model can be divided into multiple analysis units.
[0091] S304, importing material information into each analysis unit to obtain a transition model of the target element.
[0092] Specifically, the thickness of the target component may be measured first, and then the properties of the steel (E=2.1E+05, NU=0.3, RHO=7.83E-9) may be associated with the target component.
[0093] S305, importing the restriction information into the transition model, and outputting the description file of the target component.
[0094] For example, you can first create a load set named: force_case1; define the card type: HISTORY; and assign the force and moment of the hard point connecting the chassis and the target element under working condition 1; create a boundary condition load set and name it SPC, constrain the front axle weldment and the body connection point in 1-6 directions of freedom, card type definition: INIYIAL_CONDITION; create OUTPUTBLOCK and name it output1, set the OUTPUT card, output node displacement U, mesh stress S and other parameters; create an analysis step and name it Step-1, check the load set force_case1 defined by S1 and output1 defined by S4; set the analysis type to Static; turn on the nonlinear switch; set the analysis increment step to 0.1, which means that one type of restriction information is associated with the target element. The association method of the remaining restriction information is similar to the above method and will not be repeated here.
[0095] S306, performing finite element analysis on the description file to obtain the maximum stress of the target element.
[0096] For example, the abaqus solver can be used to perform finite element analysis on the description file and output the maximum stress of the target element.
[0097] Specifically, an increasing force can be applied to the geometric model until the geometric model undergoes irreversible deformation, and the value of the force applied to the geometric model at this time is collected. The above operation is repeated to collect multiple force values and take an average value, which is used as the maximum stress of the target element.
[0098] Optionally, incremental forces in different directions may be applied at different positions of the geometric model until the geometric model undergoes irreversible deformation, and the force value applied to the geometric model at this time is collected, and the above operation is repeated to collect multiple force values and take an average value, which is used as the maximum stress of the target element. It should be noted that the force application method can be adjusted according to demand and is not limited here.
[0099] S307, performing strength evaluation according to the maximum stress of the target element to obtain strength information of the target element.
[0100] Specifically, by comparing the maximum stress with a preset stress-intensity relationship table, the strength information of the target element can be obtained.
[0101] In the above embodiment, the appearance information and attribute information of the target element are first obtained, and then the geometric model of the target element is constructed using the appearance information, and then the geometric model is divided into multiple analysis units, and then the material information is imported into each analysis unit to obtain a transition model, and finally the restriction information is imported into the transition model, and the description file of the target element is output, and the description file is solved to obtain the strength information of the target element. In this way, before the development of the finished vehicle is completed, the strength analysis of each component of the vehicle can be completed using only the geometric model of each component, which greatly increases the efficiency of the strength analysis of the automobile components and reduces the cost of the strength analysis of the automobile components.
[0102] The above are some specific implementations of the automobile component strength analysis method provided in the embodiments of the present application. Based on this, the present application also provides a corresponding device. The device provided in the embodiments of the present application will be introduced from the perspective of functional modularization.
[0103] See also Figure 4 The structural schematic diagram of the automobile component strength analysis device 400 shown in FIG. 4 includes: an information acquisition module 410, a model construction module 420, an information import module 430 and a strength solution module 440, wherein:
[0104] The information acquisition module 410 is used to acquire relevant information of the target element; the relevant information includes shape information and attribute information of the target element;
[0105] A model building module 420, for building a geometric model of a target element according to the shape information;
[0106] The information import module 430 is used to import the attribute information into the geometric model and output the description file of the target component;
[0107] The strength solving module 440 is used to solve the description file to obtain the strength information of the target element.
[0108] The above-mentioned automobile component strength analysis device first obtains the appearance information and attribute information of the target component, then uses the appearance information to build a geometric model of the target component, and then imports the attribute information into the geometric model to obtain a geometric model with various attributes of the target component, and finally outputs a description file of the model, and solves the description file to obtain the strength information of the target component. In this way, before the development of the finished vehicle is completed, the strength analysis of each component of the vehicle can be completed by only using the geometric model of each component, which greatly increases the efficiency of the automobile component strength analysis and reduces the cost of the automobile component strength analysis.
[0109] See also Figure 5The structural diagram of the information import module 430 is shown, wherein the information import module 430 includes:
[0110] A meshing submodule 431 is used to divide the geometric model mesh into a plurality of analysis units;
[0111] The information import submodule 432 is used to import the attribute information into each analysis unit and output the description file of the target component.
[0112] Specifically, the information import submodule 432 includes: a first import unit, used to import material information into each analysis unit to obtain a transition model of the target element; a second import unit, used to import restriction information into the transition model and output a description file of the target element.
[0113] The above-mentioned information import module first divides the geometric model into multiple analysis units, then imports the material information into each analysis unit to obtain a transition model, and finally imports the restriction information into the transition model and outputs a description file of the target element. Dividing the model into multiple analysis units and importing the material information separately can more accurately describe the material of the collective model. Importing the attribute information can enable the final geometric model to completely replicate the target element in the actual vehicle. The description file exported based on this geometric model can describe the target element more comprehensively and completely, so that the strength of the target element subsequently obtained based on this description file is more accurate.

[0116] The strength evaluation submodule 442 is used to perform strength evaluation according to the maximum stress of the target element to obtain strength information of the target element.
[0117] The above strength solving module first solves the maximum stress of the target component, and then makes a strength judgment based on the maximum stress. The maximum stress provides a basis for the strength judgment, thereby increasing the accuracy of the strength judgment.
