摘　　要：为了确定某大型冲压机支撑架设计的合理性及工作时的应力分布和变形情况,首先根据冲压机的结构特性对模型作了简化处理,然后基于有限元分析软件ANSYS对冲压机结构进行了优化分析,得到了冲压机工作在最大载荷下的应力大小、应力分布及机架变形情况。通过分析应力云图和变形曲线,得出该冲压机外架能够满足正常的工艺需求,但整体上应力分布范围较广仍有优化的空间。In order to study the rationality of a large stamping machine＇s carriage, stress distribution and deformation on working condition, the model was simplified based on the characteristic of the stamping machine structure at first, and then conducted analysis of the structure of this machine by using finite element software ANSYS, stress value and distributions of this machine under the maximum working-load, deformation of the structure was obtained. Analysis of the stress contour and deformation curve shows the conclusion that the outer frame of the machine can meet the normal process requirements, while it remians a wide range of stress distribution with optimized space as a whole.
