齒輪箱為風力發電系統重要零件之一，其每年損壞率僅一成，卻是造成風力發電系統停機之首要原因。本文利用轉移矩陣法針對風力發電傳動系統進行動態特性分析，其特點為適合應用於串聯式傳動系統，且分析模型之參數經等效公式計算，故分析時間低於有限元素法。
本論文針對承載容量為2MW之風力發電齒輪傳動系統進行動態特性分析，齒輪傳動系統由二階式行星齒輪系與平行軸齒輪系組成，文中包含轉移矩陣法公式、行星齒輪系等效公式、傳動系統三維模型建立及分析參數求取，並藉由上述公式及傳動系統參數進行實例分析。
實例分析探討分析模型加入齒輪嚙合剛性參數、考慮不同行星齒輪組裝結構、增加軸承徑向剛性及彎曲剛性參數、葉片及發電機參數、行星齒輪數量，對系統動態特性之影響。透過上述分析方法及結果，提升設計初期之分析效率，排除可能造成齒輪箱失效之問題，可提升風力發電傳動系統穩定度。

One of the important components of the wind turbine is gearbox that its failure is the main reason to cause downtime for the wind turbine, however, the failure rate of the gearbox is less than the other subsystem in the wind turbine.

The main purpose of this study is the dynamic characteristics analysis of the gearbox of the wind turbine by the transfer matrix method. The feature of transfer matrix method is suitable for the serial-type transmission system. The gearbox capacity is 2MW that is composed of the ordinary gear train and planetary gear train. The transfer matrix method and the equivalent formulas of the gearbox are built in this study. The parameter of gearbox is obtained by the 3D model of gearbox.

The analysis results include the natural frequency and mode shape that are not affected by the gear mesh stiffness and the assembly structure of planetary gear train. The method of this study is used to exclude the problem of gear failure that the stability of the transmission system of the wind turbine and the efficiency of the analysis procedure at the design stage is elevated.
