Joint simulation method for inversion optimization of hot stamping constitutive parameters

The invention relates to a joint simulation method for inversion optimization of hot stamping constitutive parameters, which comprises the following steps: preparing a standard tensile sample of hot tensile test equipment from a hot stamping material to obtain original tensile data; smoothing the original tensile data to obtain test tensile data; carrying out secondary development on the constitutive model of the hot stamping material, embedding a subprogram into a simulation calculation module, and carrying out flow stress updating on the subprogram; the method comprises the following steps: establishing a simulation data stream, running a subprogram for realizing automatic calling of a script in a command table for calculation, importing test tensile data into target data, determining a target function, and performing inversion optimization by using a global optimization algorithm to obtain optimal constitutive parameters. The method has the effects of accurately and quickly determining the constitutive par
