The invention discloses a high strength plate stamping springback prediction method, comprising the following steps of establishing stress-strain curve families of high strength plates through a plurality of groups of material experiments and carrying out fitting to obtain an initial material constitutive model; importing the initial material constitutive model into finite element software for U-shaped slot stamping simulation analysis and comparing simulation data with a practical U-shaped slot stamping experiment; correcting parameters of a current material constitutive model if an error between the simulation data of the material constitutive model and the practical stamping experiment exceeds a threshold, and repeating the steps; and carrying out stamping simulation on high strength plate complex stamping parts through utilization of the corrected material constitutive model. According to the method provided by the invention, a high precision stamping simulation result can be obtained.
