本文对筒形件强旋三维刚塑性有限元模拟中的关键技术问题进行了研究。精确计算了旋轮和坯料的接触轮廓, 建立了有限元网格离散模型, 给出了旋轮与坯料接触区空间约束及速度边界条件的处理方法。文中对筒形件反旋模拟的结果表明, 所提出的处理方法是可靠的。 In this paper, the key technical issues in the strong three-dimensional rigid-plastic finite element simulation of cylindrical parts were studied. The contact profiles between the rotating wheel and the billet are accurately calculated, and the finite element mesh discrete model is established. The treatment methods of the space constraints and the velocity boundary conditions of the contact area between the rotating wheel and the billet are given. The results of the anti-spin simulation of the cylindrical part show that the proposed method is reliable.
