摘　　要：运用SolidWorks软件对1600t热模锻压力机机身进行三维建模,并用ANSYS对模型进行结构分析和模态分析。通过结构分析得出结构的变形和应力分布情况,分析机身设计的合理性,找出薄弱环节,为机身的优化指明方向;通过模态分析得到机身的固有频率,避免发生共振,提取前四阶振型和模态频率,为机身的动态分析提供了参考。3D solid model of a 1600 t hot die forging press frame is established with SolidWorks. This paper analyzes the structure and modal of the model by use of ANSYS, obtains the structural deformation and stress distribution and checks the its reasonable design by the structural analysis. The weak links are found. The results show clearly the direction for future optimization. The natural frequency is obtained by the modal analysis. The first four nature frequencies and nature mode shapes are obtained. The results give a reference to the dynamic structural analysis.
