摘要
Abstract
In accordance with low precision and more remainder material in domestic forging of heavy crankshafts,the simulation for the RR upsetting process of crankshaft is carried out by 3D rigid-plastic FEM. The main reasons that make the crank hard to be filled are given through analysis of its plastic flow mode and features in the process, and a new scheme of die design to prevent from the defect generation is given. Thus,this offers a scientific basis for optimum design of the process and dies.关键词
