Abstract

The invention relates to an intelligent optimization design method for a steel wheel spoke process curve, which comprises the following main steps: S1, carrying out three-dimensional modeling on a drawing die and a reverse drawing die of a spoke, parameterizing key structures of the drawing die and the reverse drawing die, compiling a macro program, and carrying out calculation on the key structures of the drawing die and the reverse drawing die; a macro program is driven through a specified command to realize automatic modification and updating of the drawing die and the reverse drawing die; s2, performing stamping process simulation analysis on the drawing die and the reverse drawing die by using finite element analysis software; s3, performing secondary development on related programs of the drawing and reverse drawing stamping procedures, and replacing the program of the original finite element analysis software with the secondarily developed program; s4, performing high-precision approximate model fitting on the simulation model; and S5, an approximate model optimization design process framework is built in ISIGHT software, optimization design is carried out on the created approximate model, the limitation of existing process curve optimization design is broken through, and the optimal deep drawing and reverse deep drawing process curves can be quickly found.

Description

technical field [0001] The invention relates to the technical field of spoke design of automobile wheels, in particular to an intelligent optimization design method for a steel wheel spoke process curve. Background technique [0002] The wheel is an important part of the automobile, and its performance is mainly affected by the product structure and stamping process. When developing a steel wheel, it is first necessary to optimize the product structure and minimize the number of plates while meeting the product performance and cost requirements. The thickness of the material can maximize the weight reduction of the wheel. On the other hand, the production quality of steel wheels is affected by the stamping process. During the production process, the unreasonable design of the mold process may cause the product to wrinkle, crack, bulge, and thin. There is a large deviation, which affects product quality and safety performance. There are 9 processes in the production process...
