摘要：

在对63 MN热模锻压力机机身进行受力分析的基础上，以有限元分析软件ANSYS和建模软件SolidWorks为主要开发工具建立了静态下机身偏载时的受力模型，对偏载时的机身刚度及变形进行了分析及计算。基于组合机身的特点，对机身在偏载下的力进行了分析和计算，对中心载荷机身静刚度进行了计算和验证。结果表明：机身承受偏载时，立柱受力部位产生较大的变形，对于机身立柱部位与滑块的导向产生不利影响并加剧相互的磨损，得到的机身垂直静刚度值高于相对应的行业设计值。在今后的设计中，应对相应部位的尺寸及结构加以优化，增加局部的刚度。

Based on analyzing the forces acting on the frame of 63 MN hot die forging press, a static force eccentric load model was created by analytic software ANSYS and the simulation software SolidWorks as major development tools. The rigidity and deformation of the body were analyzed and calculated under the eccentric load. Based on the structural characteristics of the assembled frame, the forces of the body were analysis and calculated under the eccentric load. The static rigidity of center load body was calculated and verified. The results show that larger deformation is generated in the column position，the guiding of frame column and slider are affected badly and the abrasion between them is aggravated when the frame bears eccentric load. The vertical static stiffness value of the body is higher than the corresponding industry design value. In further design, local rigidity will be improved by optimizing the size and structure of the corresponding parts.
