摘要: | 本研究旨在探討機車在穩態過彎時之穩態行為及穩定性。本研究將發展兩個機車的運動模型,過彎時的穩態運動模型及過彎時的動態運動模型,並配合電腦輔助模擬分析,探討其轉向參數、騎士於過彎時所需施加之轉向力矩及穩定性。利用本研究所發展之模型,更可探討機車在載人或騎士有重心偏移的情形下,對機車過彎時之穩態行為及穩定性所造成之影響,並比較騎士以不同騎姿過彎時,機車之轉向參數、轉向力矩及穩定性之差異。最後應用田口法,對機車之設計參數進行最佳化調整,期望能以更有系統之實驗設計法,獲得更有用之設計資訊,進而提升機車之過彎速度。 The purpose of this study is to understand the steady-state behavior and the stability of motorcycle while cornering. The model of steady-state turning and the model for the stability analysis while turning for motorcycles have been developed in this study. By using these models cooperatively, not only the steady-state behavior of motorcycle can be determined, also the stability of motorcycle while turning can be evaluated. The turning parameters, the steering torque exerted by the rider, and the stability of motorcycle, then, could be analyzed numerically. The effect of the rider lateral movement including the comparison of the rider position and the presence of the passenger on the steady-state behavior and the stability of the motorcycle are discussed. Finally by using the Taguchi approach, the design parameters of motorcycle can be better adjusted to increase the speed of motorcycle and to provide valid information of the design parameters and the cornering speed of the motorcycle. |
