獨立式懸吊機構之空間運動分析

Spatial Kinematic Analysis of Independent Suspension Mechanism

指導教授 : 尤正吉

摘要


本研究對一般小型車常見之獨立式懸吊系統,包括雞胸骨式與麥花臣式懸吊系統,利用懸吊導數法進行空間運動之分析,首先針對各式懸吊分別建構四分之一車、二分之一車和全車之懸吊空間數學模型,利用懸吊導數法求解車身與輪胎相對速度之比例關係,以獲得輪胎姿態改變量,再利用桿長不變原理分析懸吊系統接點變化的情況,並以懸吊導數法找出車輛在轉彎與起步時車身的瞬心軸,接著再利用ADAMS/Car電腦輔助模擬軟體驗證數學模型。最後利用全車懸吊模型,於車身發生翻滾與俯仰運動時對於全車懸吊機構的耦合影響,並歸納出不同形式的懸吊系統的運動特性。本研究從空間懸吊之數學式,探討懸吊系統之運動,分析之結果可作為修正懸吊機構設計參數的依據以及作為車輛動態分析之平台。

並列摘要


This study analyzes the motions of independent suspension mechanism, including Double-Wishbone type and Macpherson Strut type, usually found in general-purpose passenger cars. This study builds space suspension mechanisms through kinematic analysis of vehicle suspension mechanisms including quarter-car, half-car and full-car. Kinematic analysis of suspension derivative method can be used to find the body-wheel movement relationships and the instant axis. Then the characteristics of different independent suspension systems are compared with the simulation of ADAMS/Car software. Therefore, the design parameters of vehicle suspension can be modified according to results of analysis; in addition, this study can provide a platform for vehicle dynamic analysis.
