Research of Car Body Component Welding Simulation Technology

Abstract

Welding deformation is a key problem in the manufacturing of car body parts. The accurate detection and effective control of welding deformation are crucial to ensure the quality of car body. Unreliable welding positioning tooling and immature process may lead to welding deformation due to uneven component heating, and uneven technical level of workers. Welding simulation technology with the help of computer simulation, in-depth analysis of the temperature field and stress field changes in the welding process, can accurately predict the welding deformation and defects, and then optimize the welding process, and reduce the production cost. In this study, we construct an accurate 3 D model, use the numerical calculation method to solve the physical field changes, and improve the model combined with experimental verification. The research results are expected to obtain optimized welding process parameters, significantly reduce welding defects, improve the quality and reliability of car body parts, and lay a solid foundation for promoting the high efficiency and intelligent development of car body manufacturing.
