摘 要: | 应用Matlab软件的语言和图形功能,在频域和时域内对二自由度车辆多状态变量进行了动力学仿真。仿真结果表明,低速时,车辆动态特性呈过阻尼状态;高速时,呈欠阻尼状态,各状态量响应在工作频带内出现谐振,恶化了车辆的操纵稳定性。

Abstract: | This paper presents a multi-variable dynamic simulation of two degree-of-freedom vehicle applying the program and function of graphic with Matlab. Simulation shows that when at low spead, vehicle dynamic characteristics is in over-damping state and when at high spead, in under-damping state. Each state variable response appears resonance in working frequency domain, which deteriorates the vehicle handling and stability. |
