The simulation technology of the material forming process is a key technology for realizing the process optimization design of parts and improving the product development and production quality and efficiency. In the traditional manufacturing industry, the specific gravity of parts produced by a material forming mode is large, but the special processes of material forming, such as casting, forging, welding, heat treatment and the like belong to special processes, and the special process is characterized in that the quality of manufactured products cannot be verified by supervision or measurement and can only be displayed in the process of delivering and using the products, so that great risks are brought to the development, production and use of the products, and the reliability of the products is even influenced. The forming and modifying processes of the product generate tissue stress or internal defects, the defects are hidden in the product to form a product hidden crisis, and the parts can fail at any time in the using process, so unpredictable serious results are caused.
The process simulation technology is one of the most effective means for improving the product quality, however, an accurate process simulation result must depend on accurate simulation parameters, especially boundary condition parameters set in the simulation pretreatment process, and an accurate parameter range is difficult to obtain by means of a traditional test means.

s3, setting a target value of the confidence coefficient of each current process simulation;
s4, forming a summary table by the simulation boundary condition parameters and the confidence degrees associated with the simulation processes through a simulation data management module and outputting the summary table;
s5, performing data screening on the output summary table according to the confidence coefficient target value, eliminating simulation cases below the confidence coefficient target value, and eliminating the simulation cases from the simulation data management module;
s6, determining the range of the boundary condition parameters of the screened cases with high confidence coefficients according to a union mode;
and S7, in the subsequent process simulation process, continuously applying the case with higher confidence coefficient to a simulation data management module for processing, summarizing, screening and analyzing various data, gradually optimizing the range of boundary parameter values, and finally solidifying the parameter values to form an accurate boundary condition parameter database.
