Modal Analysis of High-Speed Helical Gear of Wind Turbine Driven System

摘要

In order to increase reliability of wind turbine driven system,the 3D solid model of high-speed helical gear of wind turbine driven system for analysis was created by using UG software. The intrinsic vibration of the gear was researched by using ANSYS software based on vibration mechanics theory and finite element method. The natural frequency and modal vibration shape of the gear were calculated,and the characteristics of the vibration shapes were analyzed. The results reflected dynamics characteristic of the high-speed helical gear,established basic of dynamic response calculation and analysis for the gear driven system,and provides a reference for the gear driven system fault diagnosis.
