中文摘要：介绍了一火摆动辗压的工作原理和优越性。在摆辗机上预锻制坯是一火摆动辗压成形的关键。通过力学计算和有限元分析，选出最佳摆角?酌 为3°。数值模拟结果可以为开发该工艺设备确定主参数提供理论依据。
英文摘要：The working principle and superiority of the one-heat rotary forging are introduced. The key process of the one-heat rotary forging is black making of the automobile′s half shaft on the rotary forging machine. Through the mechanics calculation and finite element analysis, the appropriate dip angle of the top die is determined, which is 3°.Numerical simulation results can be regarded as the theoretical basis for defining main parameters when these series of machines are developed.
