Method for analyzing structural performance of sheet metal part

The embodiment of the invention provides a sheet metal part structural performance analysis method, which comprises the following steps: performing stamping simulation on a sheet metal part to obtain a stamping simulation model of the sheet metal part; thickness change data and plastic strain data of all positions of the sheet metal part are determined through the stamping simulation model; based on the geometric model of the sheet metal part, determining an initial structure analysis model of the sheet metal part; mapping the thickness change data and the plastic strain data to the initial structure analysis model to obtain a target structure analysis model of the sheet metal part; and analyzing the structural performance of the sheet metal part through the target structural analysis model. According to the technical scheme provided by the invention, the sealing performance of the crankcase can be conveniently and quickly tested, so that design optimization is carried out for the crankcase.
