Abstract: | 本研究之目的在探討一種可側傾式三輪機車穩態過彎之行車特性,分析不同行車狀態時,轉向力矩及轉向特性之變化及其主要影響之因素。首先,本研究將針對一種兩前輪轉向的可側傾式三輪機車(如Piaggio MP3),建立其幾何模型以及穩態過彎時之運動模型,並配合電腦輔助模擬分析,探討其行車狀態、轉向力矩及轉向特性。其次,比較與討論無側傾式三輪車輛、一般二輪機車與可側傾式三輪機車行車狀態與行車特性之異同。最後,經由調整機車幾何參數、輪胎角度、側傾機構尺寸等設計參數,觀察其對三輪機車穩態轉向行車特性之影響。本研究對三輪機車行車特性之分析,可以幫助了解其設計參數之影響,將會有助益於可側傾式三輪機車設計參數之決定。 The purpose of this study is to understand the steady-state cornering behaviors of a tilting three-wheeled vehicle. Firstly, the model of steady state cornering for a tilting vehicle which has two directional front wheels like Piaggio MP3 has been developed in this study. The cornering parameters, the steering characteristics, and the steering torque exerted by the rider are analyzed numerically. The comparison of non-tilting three-wheeled vehicle, two-wheeled motorcycle and the tilting three-wheeled vehicle are discussed. Finally, the effects of the geometric parameters, wheel alignment, mechanism parameters on the steady state cornering are discussed. The steady state cornering characteristic graphs are presented, and need to integrate driving behaviors and characteristics, in which the steady state cornering characteristics can be expressed apparently. The results of this analysis could be useful understanding the major effects of the design parameters and helpful for further design of tilting three-wheeled vehicles. |
