Intelligent optimization design method for steel wheel spoke process curve

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 fittin
