| 摘 要： | 为了掌握轴承的动力学特性,实现转子轴承系统的非线性动力学设计,提出了附着极限压力边界条件,将 Reynolds 方程的求解问题转化为可分离变量的二阶非线性方程,得出了轴承油膜力与载荷相平衡的油膜压力,解释了油膜力的作用机理,为转子轴承系统的非线性动力学设计打下了基础.

| Abstract: | According to the limit pressure boundary condition of a journal bearing a reynolds equation can be changed to a 2nd order nonlinear differential equation,in which variables can be separated.The expression of the film force of limited length journal bearing can be obtained by integrating the equations set.The inertia co- efficient and squeeze coefficient are defined to express the inertia force and the squeeze force of the film force respectively.The film force can explain the mechanism for film force clearly and laid the foundation for further study of the dynamic characteristics of the nonlinear rotor bearing system. |
