SIMULATION ANALYSIS OF GEAR BOX OF WIND TURBINE BASED ON FLEXIBLE MULTI-BODY DYNAMICS

The subject of this paper is the numerical simulation of the gear box of a MW-class wind turbine. The aerodynamic loads analysis of wind turbine was calculated by applying Pitt-Peter theory and the co-simulation for vibration performance was carried out by combining the MATLAB/SIMULINK mathematical model of drive system and the ADAMS flexible multi-body dynamics model to get the Load data of the low-speed shaft, which were put into the Romax transmission system model for gearbox numerical simulation analysis. The results shows that the co-simulation method can well simulate the overall performance of wind turbine, and the simulation data can be effectively used for the analysis of wind power gear box. The research of this paper provides a new idea for large-scale wind turbines gear box analysis.
