摘要

本研究以個人快速運輸系統為設計平台，訂定一懸吊設計流程，並依此進行懸吊性能探討，依照此流程可以根據需求設計出一個符合懸吊運動參數範圍的基本底盤系統。在設計之前先將懸吊機構的運動方式轉換為數學模型，並利用此數學模型建立懸吊模擬程式，藉此找到懸吊系統的各個參數對於懸吊定位角及轉向性能的影響，了解其影響後就能針對設計需求進行懸吊系統以及轉向系統的設計。機構設計完成後，進行懸吊彈簧的探討及選用，對車輛的懸吊剛性及側傾剛性進行計算，了解整車側傾量是否達到標準，以上結果皆利用車輛動態分析軟體Adams/Car驗證，最後進行實車測試驗證轉向設計達到目標。

This study uses a Personal Rapid Transit as a design platform to establish a suspension design process and to investigate the suspension performance. According to this process, a system that meets the parameters of the 　　　suspension movement can be designed. Before the design, the suspension mechanism is first converted into a mathematical model. A mathematical model is used to create a suspension simulation program to find the impact of various parameters of the suspension system on the suspension positioning angle and steering performance. The suspension system and the steering system then can meet the design requirements. After the mechanism design was completed, the suspension springs were discussed and selected. The vehicle's suspension rigidity and roll stiffness were calculated to see if the vehicle's roll reached the standard. The design results were validated using the vehicle dynamics analysis software Adams/Car. Finally, the real vehicle test verifies that the steering design achieves the goal.
