基于MATLAB/SIMULINK的车辆高速转向运动变化仿真

Research of Vehicle Steering Motion Change Simulation Based on MATLAB/SIMULINK

MATLAB是一种功能十分强大的科学计算软件。自产生之日起,就以其强大的功能和良好的开放性在科学计算诸软件中独占鳌头。如今,MATLAB已经从最初的矩阵计算工具渗透到科学与工程计算的多个领域,在自动控制、信号处理、图像处理等多个方向都有广泛的应用。为此,通过利用Matlab/Simulink软件,以三自由度汽车非线性动力学模型为基础,对车辆在高速转向行驶时姿态的变化建立仿真模型,并取得良好的仿真效果,为汽车在高速转弯时行驶的安全性提供了理论依据。

MATLAB is powerful software. Since it appears,it is at the top of computer softwares as it has powerful function and open. Today MATLAB has used in many fields as auto-control,signal processing,picture processing and so on.This paper introduce mainly the characteristic of software MATLAB/SIMULINK,and using it to establish the dynamical model of a vehicle system with 3 degree under the high speed steering motion change. The simulation model are acquired the better results and afford the academics foundation for the safety of vehicle on high speed steering motion.
