摘要

本文主要研究目的，即是在探討當混成動力系統加入原始機車車身設計後，其靜態與動態反應之情況。然而車身的功能猶如人類的骨架，故車身設計之優劣將直接影響機車的操控性與安全性。因此，本文即利用ANSYS與MATLAB針對車身結構進行靜態、模態、動態分析，探討車身結構脆弱之處與行駛時之動態響應，並評估機車騎乘舒適性與操控性。此外，還針對懸吊彈簧參數進行舒適化設計。

本文之研究成果，可使機車主車身在混成動力系統安裝後，能避開引擎經常運轉之頻率而避免產生結構共振現象；且若依據騎乘舒適性、操控性指標來設計懸吊系統參數，則可得到優良之機車動態性能。

The main purpose in this study is discussion after the hybrid power system to join the original body structure design, with excellent static and dynamic characteristics.

Although the body on motorcycle like humanity's skeleton, therefore fit and unfit quality of the body design will affect to the control and the security directly. Therefore, this study namely carries on the static analysis, the modal analysis, the dynamic analysis, using ANSYS and MATLAB in view of the motorcycle's body structure, discusses which frail place and the travel dynamic response, and the appraisal the rides comfortableness and the controls on motorcycle. In addition, but also aims at the comfortable design on the suspension spring parameter.

The results of this study can avoid frequency of the engine frequent revolution to avoid having the structure resonance, after the hybrid power system to join the body structure design,, If design the suspension system parameter by ridding comfortableness and controlling index, then may obtain excellent dynamic characteristics.
