摘　　要：在建立旋转机械转子支承系统的有限元模型的基础上 ,分析了这两种轴承在工作转速下的裕度和随着载荷、油温、转速及几何参数变化的稳定性变化规律。讨论了在设计参数及运行条件下椭圆轴承和三油楔轴承在中、轻载区的稳定性裕度。On the basis of establishing the finite element mode l of rotating machinery rotor supporting system, allowance under the working speed and the law with the changes of load, Oil temperature, speed and geometric para meter of two kinds of bearings are analyzed. The stability allowance of elliptic bearing and three oil wedge under the design parameter and operating condition in middle and light loading area is discussed. New investigation is done for th e judgement of lost stability speed.
