Method and device for matching automobile steel rim material

Abstract

The invention relates to the technical field of automobile, in particular to a method and device for matching automobile steel rim material. The method comprises the step of establishing a 3D model of a wheel steel rim, establishing a material mechanical performance parameter library of the wheel steel rim, combining the wheel steel rim 3D model and the parameter library, generating a finite element stress and strain calculation model, using the finite element stress and strain calculation model to analyze stress and strain nephogram distribution of the corresponding material on the wheel steel ring 3D model, using Miner-Brown fatigue life model for analysis to acquire a fatigue life nephogram distribution of wheel steel ring 3D model, and selecting the material corresponding to the longest fatigue life in the wheel steel ring 3D model as the automobile steel rim material. The device for matching automobile steel rim material comprises a 3D modeling unit, a parameter library unit, a stress and strain modeling unit, a stress and strain analysis unit, a fatigue life analysis unit and a material selection unit. The method and device for matching automobile steel rim material can accurately match up best materials for steel rim spoke and steel rim, and enhance the fatigue life of the wheel steel rim.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for matching automobile steel ring materials. Background technique [0002] In the wheel rim production line, the steel plate goes through cutting, chamfering, coiling, flattening, butt welding, slag scraping, rolling, flaring, rolling, expanding, punching, magnetic flaw detection, assembly, and correction points Welding, synthesis feeding, synthesis welding, welding slag removal, final inspection and other processes to provide users with wheel rim products. In order to meet the needs of light weight, some wheel rim manufacturers have optimized the structural design of the wheel spokes and rims, and carried out high-strength optimization on the materials of the rims and spokes. After optimization, it was found that the replacement of materials was not very good. The fatigue life of the wheel steel rim is greatly improved, and in some cases, the fatigue life ...
