| Abstract: | A dynamic analysis model was established for 2-stage star gear train,wherein the transmission error and the time-varying stiffness and backlash were considered.Using ODE45 integration method,the nonlinear differential equations with multiple backlashes were solved.The nonlinear dynamic behavior,which leads to chaos from harmonic vibration,non-harmonic vibration,period-doubling vibration and quasi-periodic vibration by changing frequency excitation of the system,was discussed thereof. |

| Keywords: | aerospace propulsion system star gear train nonlinear vibration chaos dynamic characteristic |
