摘　　要：某锻造液压机采用双柱斜置式预应力组合机架,为了合理的预紧机架,全面掌握机架的整体性能,给后续的整机设计及优化提供理论参考,主要选取镦粗、扩孔和拔长3种典型工况进行分析。首先应用I-DEAS软件建立三维模型,然后导入MARC软件中进行接触算法计算,每种工况分为中心载荷和可能的最大偏心载荷等情况进行加载计算。三维模型结果显示了在不同工况下立柱与上下梁的开缝大小及开缝长度,计算结果显示扩孔工况不开缝,镦粗和拔长工况分别有0.21和0.12 mm开缝。因此在压机实际运行时,应控制镦粗工况前后偏载的偏心量。压机通过实际的锻造使用证明了前期的分析计算的可靠性。The hydraulic pressure machine with double column and inclined structure frame was studied. In order to pre-tight frame rea- sonably, master the overall property of the frame comprehensively and then provide theoretical reference for the subsequent design and op- timization, three traditional conditions of upsetting, reaming and pulling were mainly analyzed. Firstly, the three-dimensional model was built by software I - DEAS, then the model was imported into MARC and calculated by contact algorithm. Each condition was calculated under the center load and the maximum eccentric load. The three-dimensional model shows the size and length slit between the upper and lower beam under different conditions. Calculations show that the reaming condition has no slit, and the upsetting and pulling conditions have 0. 21 mm and 0. 12 mm slits respectively. Therefore, in the practical operation, the front and back eccentricity during upsetting should be controlled. The above calculation is proved to be feasible by actual forging process of the machine.
