Abstract：A nonlinear dynamic model of spur gear transmission system is built with consideration of gear mesh stiffness,backlash,error of tooth mesh and external excitation.The vibration differential equations of transmis-sion system are derived by Lagrange equation.Time domain waveform,spectrogram and phase graph of gear transmission system are obtained by Runge-Kutta method.It is studied that parametric variation such as rotating speed and backlashes is influence on dynamic characteristic gear transmission system.The result shows that vibration amplitude of gear transmission system is lager and vibration is more serious with the increase of rotational speed and backlash.The conclusions lay the certain foundation for natural characteristics and dynamic response of spur gear transmission system.
