采用三维大变形热力耦合有限元法分析了不同形状的切分孔对轧件变形的影响 ,探讨了轧制过程中轧件上的变形分布 ,研究了金属的流动规律以及对轧制力能参数的影响。模拟结果和实际轧制情况一致。通过模拟金属变形过程可为不同条件下正确设计切分孔提供依据
The influence of cutting holes with different shapes on the rolling deformation was analyzed by the three-dimensional large deformation and thermal-mechanical finite element method. The deformation distribution on the rolling material was discussed. The flow law of the metal and the influence of rolling force energy parameters Impact. The simulation results are consistent with the actual rolling conditions. By simulating the metal deformation process can provide the basis for the correct design of split hole under different conditions
