Abstract :
In order to research into changes with time of dynamic characteristics, vibration response of gear driven system of wind turbine was analysed in time-domain. The method of lumped-parameter was adopted to found dynamic model of multi-degree of freedom system for the wind turbine gear driven system. Calculation method of model parameters was introduced. Meshing stiffness, damp coefficient and error excitation were calculated. The numerical simulation of the vibration system in time domain was carried out by the 4-steps Runge-Kutta method with MATLAB. Vibration responses of the system were obtained. It has guiding meaning for system optimization design.
