摘　　要：对JZ21型开式压力机进行三维建模,将有限单元法应用于此类新型开式压力机的机身受力计算和分析,并与试验结果进行了比较,验证了计算模型的正确性。在此基础上,对加强板的厚度进行优化,并研究了加强板的形状尺寸对角刚度的影响,从而达到减轻自重的效果,为结构的合理设计与改进提供了可靠的依据。D modeling of Model JZ21openback press has been introduced,in which FEM has been applied to do analysis and calculation of the frame of this new style openback press then tested results have been compared with to validate the correctness of the model.On this base,the thickness of strengthen-board has been optimized,the influ-ence of the shape and size of the strengthen-board on the angle-deformation has been discussed hence the frame weight reduced and the reliable data for the structural design and improvement available.
