【Abstract】 According to the characteristics and technical requirements of the front axle of heavy truck, the precision roll forging-die forging process design of the front axle was carried out. Based on the actual production parameters of a forging company and the finite element analysis software,the forming process was numerically simulated. In order to solve the problem of unsatisfactory filling of the joist in the simulation process, the die was improved. Finally, the physical experiments were performed to verify the accuracy of the simulation.更多还原
