| 摘 要： | 针对连杆轴瓦在工作过程中因振动造成的损坏问题,利用ABAQUS有限元软件对滑动轴承轴瓦进行模态分析,得到其在安装状态下前14阶的固有频率和振型,以及受载状态下前14步增量步的振动频率。根据轴瓦的实际工况将镀层材料改为复合材料并进行适当优化,提高了轴瓦的固有频率,缩小了振动变形区域,可有效预防轴瓦在工作过程中产生振动损坏等现象。

| Abstract: | Aiming at the damage caused by the vibration of the connecting rod bearing bush during work,the ABAQUS finite element software is used to perform a modal analysis on the plain bearing bearing bush,and the natural frequency and mode shape of the first 14 steps in the installed state were obtained,the vibration frequency of the first 14 incremental steps under load.According to the actual working conditions of the bearing pad,the coating material is changed to a composite material,and appropriate optimization is performed to increase the natural frequency of the bearing pad and reduce the vibration deformation area,which can effectively prevent the vibration damage caused by the bearing pad during the working process. |
