Abstract

To improve the stability and effectiveness of the gearbox of wind turbine, it is necessary to investigate the effects of design parameters on dynamic characteristics of system. According to the structure of actual example of gear driven system of wind turbine, this paper calculated the natural frequency of the system using the software of Matlab, and obtained the relationships between torsional stiffness and natural frequencies on the quantitative with sensitivity analysis. The results provide the basis for dynamic modification and a reference for fault diagnosis of the gear driven system of wind turbine.
