摘要
本文用三维刚塑性有限元法对几种不同截面的环件轧制过程进行了分析。解决了芯辊转速确定,压下量分配,咬入曲线计算及边界条件处理等问题。所得到的结果有助于深入了解环件轧制过程的机理,对实际生产和轧制设计具有一定的指导作用。
In the present paper, rolling of rings with different cross sections is analysed by using a 3D rigid-plastic finite element method. The problems met in analysis, such as determination of mandrel velocity, distribution of roll reductions, initial contact lines between ring and rolls and boundary conditions are solved. The calculated results are very helpful to more deeply understand the deformation mechanics of ring rolling process and useful in practical ring production and design of mills.
