[0071] The method may specifically include the following steps:

[0072] S101: Acquire a pre-created vehicle simulation model, where the vehicle simulation model includes a number of parts.

[0073] It should be noted that the vehicle simulation model can be a tool that uses computer technology to simulate the vehicle assembly process. It simulates and analyzes the various parts of the vehicle and their assembly relationships through mathematical models and algorithms to predict the behavior and performance during the assembly process, helping users to conduct virtual experiments before actual operations, optimize the assembly process, reduce risks, and improve efficiency. In the embodiment of the present application, the simulated assembly of parts can be achieved through the vehicle simulation model.

Through accurate modeling and simulation, it can be ensured that the size, shape and function of these parts during the assembly process meet the design requirements, thereby improving the overall quality and performance of the vehicle. In the embodiment of the present application, the parts can be analyzed by simulated assembly.

[0075] In an embodiment of the present application, a pre-created vehicle simulation model may be obtained, and the vehicle simulation model includes a plurality of parts. The vehicle simulation model may be a model composed of all parts of the entire vehicle, or a model composed of some parts of the current vehicle. The parts in the vehicle simulation model may be simulated parts.

[0076] S102: Select a target part to be analyzed from the plurality of parts, and use parts adjacent to the target part from the plurality of parts as associated parts.

[0077] In the embodiment of the present application, a target part to be analyzed can be selected from a number of parts, and parts adjacent to the target part from the number of parts can be used as associated parts. The associated parts can be parts that are in direct contact with the target part and / or parts whose spatial distance from the target part is less than a certain threshold, and the associated parts can be one or more.

[0078] S103: Determine a first measurement point set on the target part and a second measurement point set on the associated part.

[0079] It should be noted that the measurement point may refer to a specific location set on a part or component for dimensional measurement and assembly verification. These measurement points are usually key geometric feature points, such as holes, edges, surfaces, etc. By measuring the position and size of these points, the manufacturing accuracy and assembly quality of the parts can be evaluated. In the embodiment of the present application, the measurement point may be a point set on the current part for measuring the distance between the current part and other parts.

[0080] In the embodiment of the present application, a first measurement point set on the target part and a second measurement point set on the associated part can be determined. The first measurement point on the target part can be one or more, and the second measurement point on the associated part can also be one or more.

These assembly relationships determine the position, direction and function of the parts in the vehicle, and are key factors in ensuring the overall performance and quality of the vehicle. Through precise modeling and simulation, these assembly relationships can be optimized to improve assembly efficiency and product quality. In the embodiment of the present application, the simulated assembly of the target parts and associated parts can be achieved through the assembly relationship.

[0084] In the embodiment of the present application, the assembly relationship between the target part and the associated parts can be determined according to the vehicle simulation model.

[0086] It should be noted that the measured dimensional data may refer to the geometric dimensional data of a part or component obtained by actual measurement. These data are usually collected by measuring equipment (such as a three-coordinate measuring machine, an optical measuring instrument, etc.) to verify the manufacturing accuracy and assembly quality of the parts.

[0089] It should be noted that the spatial distance data may refer to the three-dimensional spatial distance between parts or measurement points calculated by simulating the assembly process in the vehicle simulation model. These data are used to evaluate the assembly accuracy and fit of parts, ensuring that the position and direction of parts during the assembly process meet the design requirements. Spatial distance data is an important output result of simulation analysis, helping users identify and solve problems in the assembly process. In an embodiment of the present application, spatial distance data may characterize the gap or face difference between a target part and an associated part. The gap may refer to the difference in spatial distance between parts, and the face difference may refer to the difference in spatial distance between a part and a reference plane. The gap or face difference may be used to evaluate the assembly accuracy and fit of parts, ensuring that the position and direction of parts during the assembly process meet the design requirements.

These data are usually determined by design specifications and manufacturing standards and are used to guide the manufacturing and assembly process of the parts. In the embodiment of the present application, the reference tolerance data can characterize the deviation range allowed by the design and can be used to evaluate the assembly accuracy and fit of the parts.

[0093] In the embodiment of the present application, the assembly result of the target part can be determined according to the matching result between the spatial distance data and the preset reference tolerance data. If the spatial distance is within the deviation range allowed by the design, it can be considered that the assembly result between the target part and the associated part is normal.

The 3DCS file contains data such as the geometric model of the part, tolerance information, and assembly relationship, and is the basis for three-dimensional tolerance simulation. The 3DCS file can be exported through CATIA. In the embodiment of the present application, the three-dimensional tolerance simulation data, that is, the 3DCS file, can be imported into the simulation analysis system to generate a vehicle simulation model.

[0130] In the embodiment of the present application, the name, code, positioning constraint, assembly point, and measurement point of each of the several parts can be determined according to the assembly data, and then the design hierarchical relationship between the several parts can be obtained according to the assembly structure, and then the vehicle simulation model can be created according to the name, code, positioning constraint, assembly point, and measurement point of each of the several parts and the design hierarchical relationship between the several parts. Among them, each part has a corresponding name, code, positioning constraint, assembly point, and measurement point, and the name, code, positioning constraint, assembly point, and measurement point can also be found and obtained by the name or code of the part.

[0131] In the specific implementation, the vehicle simulation model can be created by importing files in the simulation analysis software. The operation process in the simulation analysis software can be to create a blank model, import the 3D model file, open the software interface, click data analysis, assembly analysis, click assembly, and then click to import the 3D tolerance simulation file, a dialog box pops up, and upload the assembly tree and tree structure files. One-to-one correspondence is made between the parts and measuring points, measurement and other information in the imported file, and click Confirm. Generate the corresponding model and check the model integrity.

[0132] This application obtains the design size data and design assembly data of pre-created vehicle parts, and determines the three-dimensional design data of the vehicle based on these data, thereby generating three-dimensional tolerance simulation data, including assembly data and assembly structure. Then, the name, code, positioning constraint conditions, assembly points and measurement points of each part are determined based on the assembly data, and the design hierarchical relationship between the parts is obtained based on the assembly structure, and finally a vehicle simulation model is created. This method is efficient and accurate, and can quickly generate an accurate vehicle simulation model, reduce the time and error of manual modeling, and thus improve the efficiency and accuracy of simulation analysis.

[0133] In an optional embodiment of the present application, the S12 further includes the following sub-steps:

[0134] S31: selecting a plurality of parts of the vehicle in the simulation analysis system, determining the name and the code of each of the plurality of parts and the design hierarchical relationship between the plurality of parts;

[0138] In an embodiment of the present application, another method for creating a vehicle simulation model may be to select several parts of the vehicle in a simulation analysis system, determine the name and code of each of the several parts and the design hierarchical relationship between the several parts, select assembly points and measurement points for each of the several parts selected, set positioning constraints for each of the several parts selected, and create a vehicle simulation model based on the name, code, positioning constraints, assembly points, measurement points of each of the several parts and the design hierarchical relationship between the several parts. Among them, several parts of the vehicle can be manually selected by the user, and the user can freely set the positioning constraints of each part.

[0139] In the specific implementation, the vehicle simulation model can be created by manual construction in the simulation analysis software. Enter the assembly analysis interface in the simulation analysis software, create a blank model, add the product digital models required for assembly, and operate in the work interface to add appropriate feature points (including tooling & fixtures) for the assembly objects / assembly targets involved in Move (positioning constraints) for the next assembly. According to Move (positioning constraints), select the reference feature points of the assembly objects / assembly targets one by one, and define the degree of freedom control vectors of each pair of assembly points (input & click) to complete the positioning constraints. After the assembly definition is completed, load the sample measured data, and then perform calculations to confirm whether the assembly is correct.

[0140] This application creates a vehicle simulation model by manually selecting several vehicle parts in the simulation analysis system and determining the name, code, positioning constraints, assembly points and measurement points of each part, as well as the design hierarchy relationship between the parts. This method has a high degree of flexibility and user participation. Users can freely select parts and set positioning constraints according to actual needs to ensure the accuracy and applicability of the simulation model.

[0141] In an optional embodiment of the present application, step S104 further includes the following sub-steps:

[0142] S41: acquiring the name and the code of the target part, and the name and the code of the associated part according to the vehicle simulation model;

[0143] S42: determining the target assembly point and the target positioning constraint condition of the target part according to the name and the code of the target part;

[0144] S43: searching for the associated assembly point and the associated positioning constraint condition of the associated part according to the name and the code of the associated part;

[0145] S44: setting the target assembly point and the associated assembly point to the same coordinate, obtaining the target assembly position of the target part and the associated assembly position of the associated part, wherein the target assembly position satisfies the target positioning constraint condition, and the associated assembly position satisfies the associated positioning constraint condition;

[0146] S45: Determine the assembly relationship between the target part and the associated part according to the corresponding relationship between the target assembly position and the associated assembly position.

[0147] It should be noted that the assembly position may refer to the specific position and direction of the parts in the assembly process, which is set during the product design and manufacturing process to ensure the assembly accuracy and fit of the parts. The assembly position is usually determined by design specifications and manufacturing standards to guide the manufacturing and assembly process of the parts. In the embodiment of the present application, the assembly position of the parts in the vehicle simulation model can be reflected by the assembly position, and the assembly position can be reflected by a number of coordinates or by the relative positions between a number of parts.

The target assembly point and the associated assembly point are set to the same coordinate, that is, the assembly points of the target part and the associated part are matched so that they overlap to simulate the installation situation during actual assembly. The target assembly position of the target part and the associated assembly position of the associated part are obtained, wherein the target assembly position satisfies the target positioning constraint, and the associated assembly position satisfies the associated positioning constraint, and the assembly relationship between the target part and the associated part is determined according to the corresponding relationship between the target assembly position and the associated assembly position. In other words, after matching the assembly points of the target part and the associated part so that they overlap to simulate the actual assembly, the target part and the associated part are each limited to the positioning constraint that they should meet, so that the target part and the associated part that meet the design requirements and are simulated and assembled can be obtained, and the assembly relationship between the target part and the associated part can be determined according to the corresponding relationship between the assembly positions of the target part and the associated part at this time.

[0149] This application obtains the names, codes, assembly points and positioning constraints of the target parts and associated parts, and sets the target assembly points and associated assembly points to the same coordinates to simulate the installation situation during actual assembly. Then, based on the correspondence between the target assembly position and the associated assembly position, the assembly relationship between the target part and the associated parts is determined. This method has high precision and high efficiency, can accurately simulate the actual assembly process, and ensure the assembly accuracy and fit of the parts.

It may include the length, width, height, diameter, aperture, tolerance, etc. of the part, which is used to guide the manufacturing and assembly process of the part. In the embodiment of the present application, the dimensional data may be the dimensional data of the part preset in the vehicle simulation software, and the dimensional data of the preset part may be standard data.

In other words, the target part constructed based on the target measured size data is assembled at the target assembly position, and the associated part constructed based on the associated measured size data is assembled at the associated assembly position.

The number of the measured spatial coordinates of the first measurement point is the same as the number of the first measurement points, and the number of the measured spatial coordinates of the second measurement point is the same as the number of the second measurement points.

[0160] This application adjusts the size data of the target part and the associated part according to the target measured size data and the associated measured size data to obtain the adjusted part based on the measured size data. Then, in the simulation environment, the adjusted target part and the associated part are assembled in their corresponding assembly positions, and the measured spatial coordinates of the first measurement point and the second measurement point after the assembly are obtained, and the spatial distance data between the first measurement point and the second measurement point are calculated. Detailed measurement point and spatial distance data can be obtained to ensure the assembly accuracy and fit of the parts.

[0173] In the embodiment of the present application, the size data of the target part can be adjusted according to the target standard size data to obtain a standard target part, which is a target part constructed based on the target standard size data. The size data of the associated part can be adjusted according to the associated standard size data to obtain a standard associated part, which is an associated part constructed based on the associated standard size data.

[0174] In the embodiment of the present application, in the simulation environment, the standard target part can be assembled at the assembly position of the target part, and the standard associated part can be assembled at the assembly position of the associated part. In other words, the standard target part constructed based on the target standard size data is assembled at the assembly position of the target part, and the standard associated part constructed based on the associated standard size data is assembled at the assembly position of the associated part.

[0176] The assembly adjustment scheme may be a scheme for adjusting the assembly method of the target part, which may be determined based on the first deviation distance data and the second deviation distance data. The first deviation distance data may represent the deviation between the actual measured size of the target part and the standard size of the target part, or may represent the deviation between the assembly position of the target part and the assembly position of the standard target part. The second deviation distance data may represent the deviation between the actual measured size of the associated part and the standard size of the associated part, or may represent the deviation between the assembly position of the associated part and the assembly position of the associated target part.

[0177] In an embodiment of the present application, the size or assembly position of the target part can be adjusted according to the first deviation distance data and the second deviation distance data, and iterative simulation is performed again according to the adjusted data. When the spatial distance data, the first deviation distance data, and the second deviation distance data all meet the preset tolerance requirements, an assembly adjustment plan is formed according to the last adjustment plan.

[0178] In the specific implementation, the specific operation method can be to enter the assembly analysis interface in the simulation analysis software, click Add Sample, select the calculation sample of each part, and confirm, operate in the working interface, click Calculate, and click each measurement point after the calculation is completed to display the calculation results, and view the results.
