Problems solved by technology

[0002] At present, with more and more development projects of the company's new models, in actual projects, the solder joint data provided by the product department is only the solid ball, that is, the solder joint sphere, but does not provide the solder joint position, resulting in confusion when doing solder joint assembly. Unable to choose, the traditional method is to select two points in HyperMesh, and manually create the middle point as the welding point. For the 5000-6000 welding points of the body assembly, manual processing not only greatly reduces work efficiency, but also increases the cost of engineers. The work intensity will also prolong the project development cycle

Embodiment 1

[0027] A method for treating welding spots of a vehicle body of the present invention comprises the following steps:

[0028] S1. Use HyperMesh to establish a finite element model of the car body without solder joints;

[0029] S2. Based on HyperMesh, the welding point spacing on the car body is parameterized, that is, the welding point spacing is used as a design variable;

[0030] S3. Optimizing the layout of solder joints to obtain multiple solder joint spheres composed of finite elements;

[0031] The single solder joint sphere represents a model of a soldering range, and the model is composed of 1-3 semicircular curves.

[0032] S4. Collect and sort a plurality of solder joint spheres;

[0033] S5. Taking out the sorted plurality of solder joint spheres one by one according to the serial number and marking the solder joints;

[0034] S6. Put the solder joint sphere labeled by the solder joint into the target file.

[0035] The present invention stores a plurality of s...

Abstract

The invention provides a vehicle body welding spot processing method. The vehicle body welding spot processing method comprises the following steps: S1, establishing a vehicle body finite element model without welding spots by utilizing HyperMesh; S2, based on HyperMesh, parameterizing the distance between the welding points on the vehicle body, namely, taking the distance between the welding points as a design variable; S3, optimizing the solder joint arrangement, and acquiring a plurality of solder joint spheres composed of finite elements; S4, collecting and sequencing the plurality of solder joint spheres; S5, sequentially taking out the sorted solder joint spheres one by one according to the serial numbers, and marking the solder joints; S6, putting the solder joint spheres marked bythe solder joints into a target file, orderly storing the solder joint spheres provided by a product department through related programs, searching and marking the solder joints, and putting the solder joint spheres marked by the solder joints into the target file, so that manual creation of the solder joints is avoided, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a method for treating welding spots of a vehicle body. Background technique [0002] At present, with more and more development projects of the company's new models, in actual projects, the solder joint data provided by the product department is only the solid ball, that is, the solder joint sphere, but does not provide the solder joint position, resulting in confusion when doing solder joint assembly. Unable to choose, the traditional method is to select two points in HyperMesh, and manually create the middle point as the welding point. For the 5000-6000 welding points of the body assembly, manual processing not only greatly reduces work efficiency, but also increases the cost of engineers. The work intensity will also prolong the project development cycle. Contents of the invention [0003] The object of the present invention is to provide a method for treat...
