摘要
根据最大周向拉应力准则,应用ANSYS参数化设计语言编写的宏命令程序,对发动机悬置软垫的断裂过程进行了模拟,得出了2种步长时裂纹前进的裂尖位置及相应的裂纹轨线。
According to the maximum tensile circumferential stress theory, using the ANSYS parametric design language to program macro file, the break process of the engine suspending bearings is simulated. Also, the locations of the crack tip and corresponding crack trajectories of two different crack increments are obtained.
