摘要


本研究針對拖曳臂式獨立懸吊系統,分別建構四分之一車車輛直行與二分之一車車輛過彎之懸吊系統數學模型,利用齊次座標轉換矩陣方式分析懸吊桿件之幾何位置。接著在懸吊桿件與車身連接處加入滑塊,藉由移動滑塊來調整懸吊幾何機構的幾何型態,發展出一組依行駛狀態調整懸吊機構之可變幾何懸吊系統,達到車輛側傾時減少車身側傾力距並有效降低側傾角度;最後運用電腦輔助分析軟體ADAMS/CAR建構可變幾何懸吊系統模型,並與一般拖曳臂式懸吊系統進行模擬比較,由此模擬結果可知本研究所建構之可變幾何懸吊系統能有效抑制側傾角度,增加車輛行駛舒適性與安全性。

This study establishes the mathematical models of Trailing Arm suspension system including quarter-car for vehicle straight running and half-car for vehicle during cornering, and analyzes how suspension link geometry position by using homogeneous transformation matrix. Then install a slider at the vehicle body-side connecting portion of trailing arm so that suspension geometry can be changed by sliding the slider. This trailing arm variable geometry suspension system can reduces body roll angle during cornering. Finally, in order to evaluate the safety and ride comfort. This study establishes the variable geometry suspension system in full vehicle model by using ADAMS/CAR software. And we also compare the roll characteristic of vehicle between traditional trailing arm suspension systems and variable geometry of trailing arm suspension systems. The result shows that the roll angle of vehicle attitude can be improved by using novel variable geometry suspension.
