摩托車受外力碰撞後之運動模式與碰撞極限初探

Preliminary Modeling and Limit Study of 1m pacted Motorcycle Motion

本文首先建立摩托車一人系統之運動模式，色括座標系統、變數自由度與假設條件等。摩托車人系統運動方程式之推導係以摩托車之動力結構與運動特性為出發點，並考慮騎士的側傾與轉向扭力作用。狀態變數的求解以建立系統的狀態空間表示式進行，丈中詳細說明相關參數的計算方法及求解的速代限定、條件。其次再就騎士行為特性之轉向扭力係數作參數枝估，以建立適用於本研究模式之騎士轉向扭力係數。最後使用不同的系統初始速度、外力作用點與作用角度作為輸入，求得導致系統傾覆之捶限(臨界)碰撞力。本模式未來可作為機車車禍鑑定之參考。

This study intends to derive an impacted motorcycle-rider motion model. The model considers six degrees of freedom involved with the characteristics of front and rear frames of a motorcycle and rider behavior including lean angle, handling torque and handling velocity. 1n the state space representation, the model is solved by iterations in a discrete form. 1n order to present a case, the rider's driving parameters are calibrated by MADYMO result. Based on the model, the impacting limits are investigated in several situations. This model can act as a primary analysis tool for motorcycle accidents.
