Finally, the wave equation of the electromagnetic field of this kind damper isderived from the Maxwells equation. The magnetic flux density at the boundary isassumed to be harmonic, so the analytical result of the wave equation is solved. When therotor rotates, eddy currents flowing inside the conducting material field are caused. Thetangential force acting on the rotor because of the action between eddy currents andmagnetic field is produced. The tangential force causes a retardation torque, which leadsto the increase of power and heating effects.

Through above numerical analysis of the TiN coating/substrate system, some typical rules about the fatigue failure are found:(1) the fatigue damage of a coating/substrate system appears first on the interface, then expands along the interface and to the substrate, and finally causes the coatings broken and spalled;(2) under the cyclic loadings of tangential sliding and radial extrusion, the equivalent plastic damage on the interface is mainly generated by the shear stress and the accumulated plastic contributed by the increments of shear stress. Thus the change of the shear stress is the main factor for the contact fatigue damages of coating/substrate system;(3) the frictional coefficient, external loading and coating thickness have some influence on the carrying capacity and contact fatigue life for a coating/substrate system.

通过对TiN涂层／基体系统的数值模拟分析，得到了涂层／基体系统疲劳失效的一些典型规律：(1)、涂层基体的初始损伤首先出现在交界面处，然后沿界面并向基体中扩展，最后导致涂层断裂而发生剥落失效；(2)、在切向滑动和径向挤压循环载荷作用下，交界面处的塑性损伤主要是由剪应力τ产生，塑性累积也是由于△τ的变化引起，说明循环过程中剪应力变化是影响涂层接触疲劳破坏的主要因素；(3)、材料摩擦系数、外界载荷大小以及涂层厚度都对涂层／基体系统的承载能力以及疲劳寿命都有一定影响。
