摘　　要：利用有限元分析软件Msc.superform来模拟三通阀体零件不同多向加载方式的成形过程。通过对多向同步加载、多向分步加载、多向顺序加载3种不同成形方式的时间——速度图、金属流动速度矢量图以及加载过程中挤压力曲线的比较,得出了多向顺序加载为最佳的工艺方案。节省了能源,材料利用率大大提高,其经济效益和社会效益更为可观。The part coming to simulate the forming process of three ways valve bodies in various multidirectional loading ways by using Finite Element Analysis Software Msc.superform Through the compare of the time-speed figures and the metal flow velocity vectogram that formed under the three forming ways, including multidirectional synchronic loading, multidirectional sub step loading, multidirectional sequential Loading and the compare of pressure curve during loading process, all compare shows that the multidirectional sequential loading process is the best handicraft resolution.
