摘　　要：针对电机滑动轴承的动态特性及油膜稳定性,采用压力扰动法计算得到动态特性系数值,并分析了结构参数对其的影响;同时,针对油膜稳定性,计算得到了失稳转速,分析了结构参数对其的影响。计算结果表明:需要选取合适的偏心率和宽径比来保证轴承-转子系统的稳定性,为电机滑动轴承的结构设计提供了一定参考价值。According to the dynamic characteristics of motor sliding bearing and its oil film stability,the pressure disturbance method is used to calculate the dynamic characteristic coefficient value,and the influence of structural parameters on it is analyzed.At the same time,for the oil film stability,the instability speed is calculated,and the influence of structural parameters on it is analyzed.The results show that proper eccentricity and aspect ratio should be selected to ensure the stability of the bearing-rotor system,which provides a certain reference value for the structural design of motor sliding bearings.
