摘要

本研究針對雞胸骨獨立式懸吊系統，分別建構1/4車車輛直行與1/2車車輛過彎懸吊系統之數學模型，利用向量迴路方程式分析懸吊桿件之幾何位置對車身翻滾中心及輪胎瞬時中心的影響。接著在車身與懸吊之接點處加入滑塊，使懸吊機構幾何能隨滑塊滑動而改變幾何，發展出一組可隨行駛狀況調整之可變幾何懸吊系統，達到直線行駛時較小輪胎外傾角變化與轉彎時車身產生較小翻滾力矩之要求，並藉由電腦輔助工程分析軟體ADAMS進行驗證。

This study establishes the mathematical models of quarter-car for vehicle straight running and the half-car for vehicle during cornering, and analyzes suspension link geometry relative to roll center and instantaneous center by using closure equation. Then installs a slider at the vehicle body-side connecting portion of the control arm, so that suspension geometry can be changed by sliding the slider. This paper is to suggest a variable geometry suspension in accordance with the running condition to reduce the variation of camber and the rolling moment of vehicle body, and then compare the analysis results with ADAMS/CAR software.
