摘要
为得到发动机轴承载荷,用EXCITE PU软件对某发动机的曲轴进行仿真,计算得到轴承的EHD力,并根据轴承受力和力矩的情况,选取相应的危险曲轴转角,将对应转角下的曲轴轴承载荷映射到有限元网格上,进一步使用Abaqus对主轴承壁进行强度和疲劳分析.
To obtain the engine bearing load, the software EXCITE PU is used to analyze the crankshaft and the EHD force of the bearing is obtained. The dangerous crankshaft angles are selected based on the bearing force and moment, and the bearing load is mapped to the finite element mesh to calculate the stress and safety factor of main bearing wall by Abaqus.
