Based on the Autoform simulation software,the numerical simulation and forming simulation of the outer plate of the hood of the automobile were studied,and the simulation results of the outer plate of the hood were analyzed and some parameters were optimized,so that the simulation results were more in line with the actual production application.It is mainly for the technical research on the cracking,wrinkling and other problems that may occur in stamping and forming,and according to the numerical simulation results,the area of technical problems such as cracking caused by excessive drawing sheet thinning is predicted in time,and the stamping technical measures are formulated,so as to improve the utilization rate of the hood outer plate forming die,greatly reduce the time of mold repair and operation,and make the mold repair simpler.
