摘要
在考虑滑动轴承非线性油膜力、齿轮时变啮合刚度、齿面间的摩擦力以及齿侧间隙的情况下 ,推导出了齿轮耦合的转子 -轴承系统的非线性动力学模型 ,该模型是一个包含强非线性项的非自治系统 ,蕴含着丰富的动力学内容。
Considering nonlinear fluid film forces of a journal bearing, the time-varying mesh stiffness of the gears, friction effect between tooth pairs, and backlash clearance, a geared rotor-bearing system is modeled. It is shown that the motion equation of the system is a nonautonomous differential equation with strong nonlinearity. It contains plenty of dynamic phenomena.
