Simulation Technique of Wind Turbine Dynamic Behavior using Multibody FEM Analysis

탄성 다물체 동역학 해석기법을 이용한 풍력터빈 드라이브트레인의 동특성 해석

Wind turbine requires service life of about 20 years and each components of wind turbine requires high durability, because installation and maintenance costs are more expensive than generated electricity by wind turbine. So the design of wind turbine must be verified in various condition before production step. This paper demonstrates the application of a generic methodology, based on the flexible multibody simulation technique, for the dynamic analysis of a wind turbine and its drive train. The concern of the paper is the computation of dynamic loads of wind turbine in emergency-stop condition. The finite element model is used to analyse the dynamic behaviour of the wind turbine.
