| Abstract: | Taking the theory of gear system dynamics and nonlinear dynamics as a foundation,aiming at the specific characteristics of time-varying stiffness of gear mechanism and the coupling effect of gear backlash and considering the compressive stiffness of oil film as well,the multi-bodied elasticity nonlinear dynamics model of gear mechanism was put forward based on the elastic vibration of gear tooth and the variation of meshing area of single or double gear tooth.Using the GEAR method a nonlinear vibration rese... |
