Abstract：

Based on the Parametric Technology Software UG,the rapid modeling of blade by 3D method was implemented.Using the finite element technique softwave DEFORM,a 3D thermo-mechanical coupled numerical simulation of the blade forming process was carried out.The research indicates that in the process of blade forging,there are two factors affecting temperature field,equivalent stress field and load-time curve.One is heating-up effect of plastic deformation work and friction work,the other is cooling effect of heat transfer between billet and die.It is a obvious influence on forming process of the blade under different die velocity conditions too.By comparing simulation result with the application of the results,the simulation process could be further verified to be reasonableness and practicability.
