摘　　要：用ANSYS软件对QA35Y-30液压联合冲剪机床身进行分析,得到了该机床工作危险位置的应力、应变数据,找出了影响床身最大等效应力和变形的关键结构因素,提出了改进方案。重建床身模型进行计算,床身的最大等效应力为61.8MPa,远远小于材料的许用应力;床身的最大变形仅为0.0847mm,远远小于之前的最大变形1.587mm。通过对改进前床身危险受载位置的应力和改进后床身虎口的Y向变形量作实际测量,验证了ANSYS计算模型和分析结果的正确性。Body of QA35Y-30 hydraulic combined punching and shearing machine was analyzed by ANSYS.The stress and strain of the dangerous part of the machine were studied.The key structural factors which influence the maximum equivalent stress and strain of the machine parts were researched,and improvement schemes were proposed.According to the reconstruct model of the machine body,the largest equivalent stress is only 61.8MPa and which is far less than the material allowable stress.And the maximum equivalent strain of the machine is only 0.0847mm,which is far less than the maximum strain to 1.587mm.According to the measurement on the machine jaw of Y direction after improvement the machine body is more less than before,which proves that the ANSYS calculation model and the analytical results are correct.
