摘要
建立可倾瓦推力轴承中油膜对镜板的作用力和油膜作用于可倾瓦的力矩的准静态线性和非线性动力学模型 ,并且通过对油膜压力进行二阶泰勒级数展开推导出 4 0个油膜对镜板的作用力和油膜作用于可倾瓦的力矩的线性和非线性刚度及阻尼系数 。
In this paper,quasi static linear and nonlinear dynamic modeling for perturbations of oil film on the mirror plate and the tilting pad in thrust bearings is developed.Also,40 linear and nonlinear stiffness and damping coefficients of film forces on the mirror plate and film moments on the tilting pad are derived from a second order Taylor series expansion of oil film pressure.The foundation of further studying linear and nonlinear performance and stability of tilting pad thrust bearing is built.
