Deformation Character and Analysis of Stress and Strain during Stretching Stage for Cross Wedge Rolling

Mechanical Engineering School, UST Beijing, Beijing 100083, China

摘要: 用ANSYS/LS-DYNA3D軟件對楔橫軋成形過程進行非線性有限元模擬,得到了軋件展寬段的變形特征及截面上應力應變分布規律.基于上述特征和規律,分析了軋件軸肩部分隆起及端頭凹心產生的原因,為深入研究楔橫軋的成形機理提供了依據.

Abstract: Cross wedge rolling is a complicate 3-D elastoplastic forming process. A nonlinear finite element modeling for the process of cross wedge rolling is presented with the aid of ANSYS/LS-DYNA3D. The deformation character and the distribution of stress and strain on section of workpiece during stretching stage have been obtained. On the hasis of the deformation character and the distribution of stress and strain,the shoulder and cavity on the end of work piece have been analyzed.
