Abstract

The invention relates to a method for establishing a material strengthening process database, which comprises the following steps of: obtaining a relationship between process parameters and surface state parameter distribution by applying strengthening of different process parameters to a strengthening standard test piece, performing simulation analysis on the strengthening standard test piece, performing iterative optimization on the simulation analysis by controlling an error between a measurement result and the simulation analysis, and obtaining a material strengthening process database. Calibration simulation control parameters are obtained, and then a material strengthening process database capable of giving process parameters P meeting the distribution state R according to the given geometrical characteristics T and the distribution state R of the surface state parameters is obtained. According to the method, the mapping relation between the strengthening process parameters and the surface performance can be established, and the process iteration period is shortened. The invention further provides application of the material strengthening process database.
