本研究針對複合動力系統之各動力源與動力鏈上各元件之扭力震盪進行分析，以複合動力系統增設二速變速箱之衍生構型，模擬車輛行駛時不同動力輸出源之動態響應，設計對應之方法降低其影響，以提升乘坐者之舒適性及降低機構所受之傷害。首先分析各元件與扭力震盪現象之關係，利用SimulationX軟體建立複合動力系統之車輛動力模型，並設計模擬情境決定操作模式。其次，由模擬結果，進行分析得出由於複合動力系統有多個動力輸出源，每個動力源皆有其本身無法避免的扭力震盪情形。最後，以增加轉動慣量與增設彈簧阻尼系統之方法，對系統之扭力震盪進行減振，並探討減震之效果。經由評估，採用彈簧阻尼可以有效降低複合動力系統之扭力震盪現象。經由本研究可以掌握複合動力系統之各動力源與動力鏈上各元件之扭力震盪影響，並配合減震之手段適當地減少扭力之震盪。

The research aims to develop methods for reducing torsional vibration from components of transmission system of hybrid system with additional gearboxes. The ultimate goal is to improve the comfortability of passengers and reduce harm of mechanical parts. In the beginning, we investigate the relationship between torsional vibration and each part of hybrid system. Then, we build the hybrid system model in SimulationX software and design the simulated situation for simulation. After these, we realize that there is inevitable torsional vibration from mutiple power sourses of system. Thus, this research proposes methods to decrease the torsional vibration by increasing moment of inertia and adding spring damper system in hybrid system. Then we check the consequent to know that if these methods really work by simulation. Therefore, we know that adding spring damper can effectively reduce torsional vibration of hybrid system. At last, this research can exactly reduce the torsional vibration by realizing the relationship between torsional vibration and each part of hybrid system.
