An improved model for meshing characteristics analysis of spur gears considering fractal surface contact and friction

Considering the influence of roughness on the normal contact stiffness of gears, a fractal contact model suited for gear pair contact has been established. On the basis of modified fractal contact model, the asperity contact stiffness is calculated, thus the fractal contact compliance can be obtained. By substituting the nonlinear Hertz contact compliance with the fractal contact compliance, the effects of roughness on the time-varying mesh...
