摘要

本文針對風車葉片進行系統運動模擬和結構模態與形變分析。在系統運動模擬部分，利用FAST建構出一個1.5MW、3個葉片、上風式、水平軸式的風車，然後將模型轉入ADAMS機構模擬軟體中進行分析與運動模擬，再將FAST和ADAMS分析的結果分別以三種風車運轉的狀況個別討論其風車轉速、轉子扭矩、發電機發電量，比較後有相當不錯的結果。在動態分析方面，我們在有限元素分析軟體ANSYS中建立一個完整的風車葉片模型，將FAST分析出作用在葉片上的等效力及等效力矩當作負載，可分析出整個葉片的應力分佈和變形量。

This work is concerned with the motion and load study, structural modal analysis and stress analysis for a wind mill turbine blade. The FAST (Fatigue, Aerodynamic, Structures and Turbulence) Code was applied to predict loading to a 1.5 MW three-bladed upwind horizontal-axis wind turbine. The output of FAST code containing the specified wind turbine geometric and loading information was transferred to the ADAMS program for turbine blade motion analysis and its structural modal and deformation analysis. Three wind turbine operational conditions were studied in this work in order to examine the rotation speed, torque and the electric power generation of the present wind turbine system. In addition, the turbine blade's tip deflection and the corresponding operation induced von Mises stress distribution were also presented.
