Abstract:	大型風力發電機組已為最具成效之綠能方案，然而其高可靠運轉仍需其中多階增速齒輪箱性能持續提昇。本文應用兩種電腦輔助分析軟體來探討大型風力機用多階齒輪傳動系統靜/動態特性，先以有限元素(FE) LS-DYN軟體進行多階齒輪傳動系統的模態特性與自然頻率分析；再進行以ROMAX齒輪傳動系統的靜態動態特性探討，後者也包括齒輪細部設計分析，兩種分析方法的模態形式與自然頻率結果並相互比較驗證。此外也討論齒形修整對於靜/動態特性之影響，顯示適度隆齒修整與端面導角修整皆可降低齒輪接觸負載，並改善邊緣接觸的不良情形，最後獲得 Large-scaled wind turbines have been the most successful green energy measure. Still, increasing the operation safety is heavily relying on the reliability improvement of multi-stage gear boxes. This study uses two kinds of CAE packages to analyze the sta
