| Abstract: | 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. |
