汽車多剛體系統模型動力學分析
The Dynamics Analysis of Multi-Rigid Body Models for Automobile System
摘要
本文主要對汽車結構進行動力分析研究。首先建立具9個自由度的汽車多剛體系統模型，並利用Lagrange能量法，推導出該系統之動力方程式，並轉換為狀態空間（State-space）模式，撰寫Matlab程式，分析此模型之動態特性以及加入路面衝擊函數後駕駛位置的響應，並與以ANSYS軟體求解後，相互比對分析結果，佐證本研究立論與分析之正確性。

This study deals with the dynamic behavior of automobile structural system. First, the governing equations for the 9 degrees of freedom (DOF) lumped parameter automobile model are formulated by the Lagrange energy method. Then, the governing equations are derived and converted to state-space form. Using Matlab code, the dynamic characteristics of the system and the response of driver by road impulse function input are analyzed. Meanwhile, do the same analysis by ANSYS software. Compare both results between Matlab code and ANSYS, it can be confirmed the formulation and analysis correctness of this paper.
