機車穩態過彎之行車特性分析

Abstract

本研究之目的在探討機車穩態過彎時之行車特性，分析不同行車狀態時轉向力矩及轉向特性之變化及主要影響之因素。首先，本研究將發展機車過彎時之穩態運動模型，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轉向特性，找出適合機車駕駛之行車狀態。其次，調整機車設計參數，觀察其對機車穩態過彎行車特性之影響。並對不同款式之機車：一般引擎機車、電動機車及混合動力機車進行穩態過彎行車特性之分析及比較。最後，探討騎士騎乘姿勢改變或路面傾斜的情形下，對機車過彎時之行車特性所造成之影響。本研究提出並運用穩態過彎特性圖，將行車狀態與行車特性予以整合，呈現機車穩態過彎之重要性質。本研究對機車行車特性之分析，可以幫助了解機車設計參數之影響，並會有助益於機車設計參數之決定。

The purpose of this study is to investigate maneuvering characteristics for motorcycles in the Steady state cornering. Firstly, the model of Steady state cornering for motorcycles has been developed in this study. The cornering parameters, the steering characteristics, and the steering torque exerted by the rider are analyzed numerically, and the preferable driving behaviors for motorcycles can be discussed. The driving characteristics of different motorcycle models are analyzed, including electric motorcycles and hybrid motorcycles. Finally, the effects of the rider posture and the inclination of road surface on the Steady state behavior are discussed. The Steady state cornering characteristic graphs are presented, and need to integrate driving behaviors and characteristics, in which the Steady state cornering characteristic can be expressed apparently. The results of this analysis could be useful understanding the major effects of the design parameters and helpful for further motorcycle design.
