The plug-in can be used to easily change the geometric model for rolling wheel and workpiece, complex material property, rolling depth, revolution speed and feed speed and other process parameters of parametric modeling, and realize the parameterization of the finite element simulation modelfor cold roll-beating forming, so as to automatically complete the geometric modeling, mesh, material property definition to submit a series of pre-processing process. Finally, the plug-in was used in finite element simulation, and the experiment of cold roll-beating forming is carried out. Through the comparative analysis of the simulated force, tooth profile and experiments under different parameters, the results show that the simulated force and tooth profile have the same variation with the experimental results, and the errors are below 6%, the feasibility and effectiveness of the plug-in used to establish the finite element model for cold roll-beating formingwere verified.
