【摘要】 用ＡＮＳＹＳ／ＬＳ－ＤＹＮＡ３Ｄ软件对楔横轧成形过程进行非线性有限元模拟，得到了轧件 展宽段的变形特征及截面上应力应变分布规律．基于上述特征和规律，分析了轧件轴肩部分隆 起及端头凹心产生的原因，为深入研究楔横轧的成形机理提供了依据．更多还原

【Abstract】 Cross wedge rolling is a complicate 3-D elastoplastic forming process . A nonlinear finite el- ement 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.更多还原
