本文首次对园盘剪冷剪钢板这一三维弹塑性大变形过程进行了有限元分析。在剪切过程各阶段特性、剪切力和剪切应力分布特性以及剪机几何参数对剪切过程的影响等方面取得了成果,对数值方法在剪切问题中的进一步应用有推动作用。
In this paper, the finite element analysis of the three-dimensional elasto-plastic large deformation process of the disc shears for the first time was carried out. The characteristics of the shear process, the distribution of shear stress and shear stress and the influence of the shear geometry parameters on the shear process have been achieved. The numerical method has further application in the shearing problem.
