摘要: Grazing bifurcation of a relative rotation system with backlash non-smooth characteristic is studied along the change external excitation in this paper. Considering oil film, backlash, time-varying stiffness and error, dynamical equation deduced by applying elastic hydrodynamic lubrication (EHL) Grubin theories. In process rotation, occurrence will lead to dynamic behaviors system, transform from meshing state impact state. Thus, zero-time discontinuous mapping (ZDM) Poincare are analyze local characteristics before as well after moment that appears (i.e., grazing state). Meanwhile, mechanism analyzed theoretically Floquet Numerical simulations also given, which confirm analytical results.
