Finite element simulation analysis of warm forging of spur gear

Taking 18CrNiMo7-6 spur gear as the research object, the finite element models of three schemes are established, and the warm forging process of spur gear is simulated respectively. The distribution of forming load, equal effect force field distribution and tooth cavity filling in the forming process are analyzed, the...
