Abstract：With the technology of wind turbine gearbox developing rapidly, more and more requirements for good dynamic characteristics are needed, the NVH analysis technology are important in reducing vibration noise of wind turbine gearbox. According to the principle of a megawatt wind turbine gearbox and the characteristics of the structure, considering the influence of the flexibility of structural components such as the carrier and gearbox to NVH characteristics, connecting the structure system with transmission system by the nodes of combination, NVH analysis model is established. Gear modification is done on all load conditions of spectrum in every stage, and NVH characteristics before and after gear modifying are analysed, which shows that the amplitude of vibration acceleration and structural noise of the wind turbine gearbox reduce after gear modification. The research provides basis for NVH characteristics optimization.
