| 摘 要： | 将铰接式车辆简化为6个自由度的动力学系统，建立了动态数学模型。该模型可用于分析、研究不同车速下铰接式车辆的结构参数、液压转向系统参数及轮胎特性等对其直线行驶动态特性的影响。利用该数学模型编制了仿真程序，并在计算机上分析、计算了铰接式车辆基于时间参数的动态特性。

| Abstract: | Dynamic characteristics of high speed and straight line travel of articulated vehicles were investigated in this paper. Its transverse stability is relatively poor, however,the quicker the vehicle, the worse the traveling stability because it may swing in the course of traveling. An articulated vehicle was simplified to a system with six degree of freedom and its dynamic mathematical model was established. The model can be used to investigate and analyze the influences of the changes of speed, structural parameters, hydraulic steering unit parameters and tyre characteristics on the straight line travel stability. The simulation program was compiled, which could be used to analyze and calculate dynamic characteristics of an articulated vehicle. |
