摘 要：在建立筒形件强旋有限元力学模型过程中， 旋轮与工件接触区及其边界的描述是重要的一环。 在前人研究成果的基础上， 正确地解决了这一问题， 提出了更加接近实际情况的模型， 并用该模型对强旋工艺过程进行 了刚塑性有限元分析， 揭示了工件表面的应力应变分布规律。
Abstract: The contact zone between roller and workpiece and its contour's definition are the cruxes of establishing the FEM mechanical model. On the basis of the study results of predecessors, this problem was solved rightly and a FEM simulation model of cylindrical workpiece power spinning, which conforms to the nature of the technology, was proposed and used to simulate the technology process, and the stress and strain distributions on the surface of workpiece were revealed.
