Abstract

Nonlinear dynamic analysis of wind turbine gear transmission system is very important to reduce its noise and vibration, improve the stability of the system and further explore its fault mechanism.The translational-torsional dynamic model of a wind turbine gear transmission system with time-varying meshing stiffness, meshing errors and tooth backlash was established.The system’s dynamic characteristics were analyzed with variation of excitation frequency and support stiffness using time history diagram, FFT frequency spectrum one, phase one, Poincaré section one, bifurcation one and the maximum Lyapunov exponent graph.The results showed that the system reveals single periodic motion, quasi-periodic motion and chaos, etc.nonlinear dynamic behaviors with increase in excitation frequency; the system behavior changes from a 2-period motion into chaotic one, and comes back to periodic motion with increase in support stiffness; increase in support stiffness can weaken chaotic motion, increase the periodic motion window and delay chaotic motion.
