Abstract

Embodiments of the present invention provide a clamping simulation method, device and equipment for welding jigs, and design the field of welding numerical simulation technology. The method includes the following steps: reading a dynamic jig file to generate a jig model on the interface; wherein, the The fixture model has been meshed; calculate the minimum distance between the fixture model and the meshed weldment model to realize the positioning recognition of the fixture model; according to the result of the positioning recognition and the set clamping parameters, Clamping behavior between the fixture model and the weldment model is simulated. The invention improves the simulation accuracy and efficiency, and can more scientifically and accurately reproduce the dynamic change process of the fixture in the welding process.

Description

technical field [0001] The present invention relates to the technical field of welding numerical simulation, in particular to a clamping simulation method, device and equipment for welding fixtures. Background technique [0002] The development of welding numerical simulation technology keeps improving with the accumulation of welding practical experience and the development of computer technology. The simulation of welding process can optimize and improve the design of welding structure and process, and improve the service performance of welding products. Welding numerical simulation technology is to use numerical simulation method and computer visualization technology to reproduce the physical process of welding process production in process simulation software, and to simulate and analyze it. [0003] The reproduction of the physical process of the dynamic change of the fixture in the whole welding process is an important aspect of the welding numerical simulation techno...
