摘  要:
通过对发动机前后悬置软垫进行结构分析,得到橡胶体应力云图,据此初步判定悬置软垫断裂时初始裂纹的位置,并指出其可能的断裂面,从而为进行断裂分析及裂纹扩展跟踪提供了依据。

摘  要:
Performing the structural analysis of the engine front and back suspending bearing, their stress contour was obtained. Based on that, the initial position of the crack when fracture occurs was determined, and the possible fracture surface was pointed out. It provided reference for fracture analysis and crack propagation tracking.
