摘　　要：以我国第1台最大吨位80MN双柱式快速锻造液压机为研究对象,应用Pro/E三维建模软件和ANSYS有限元分析软件相结合的方式建立有限元模型,采用接触法处理液压机各部分连接关系,分析了双柱斜置式多拉杆全预紧结构;对偏载镦粗工况下的受力状态进行了整机数值模拟,通过对计算结果分析,得到液压机的受力特点和变形规律,为液压机结构设计和优化提供依据。The first largest tonnage 80 MN double-column rapid forging hydraulic press in China was studied. The finite element model was established with the combination of Pro/E 3D modeling software and the ANSYS finite element analysis software. The connection relationship of each part of the hydraulic press was handled through the contact method. The multi-rod whole pretension structure of inclined double-column was analyzed. The stress state of eccen- tric load upsetting condition was numerical simulated. Through the analysis of calculation results, the stress state and deformation law of hydraulic press is received. It provides a basis for the structural design and optimization of hydraulic press.
