类菱形铰接式底盘动力学建模与仿真分析

摘要

Finrstly, integrom, chassis of rhombus concept off-road vehicle was studied at home and abroad. Then the article introduced structural theory of the integrally chassis of rhombus concept off-road vehicle. On this base, the articulated chassis of rhombus concept off-road vehicle was designed to make up for the passing capability of the integrally chassis. The dynamic model of the articulated chassis was built by the software ADAMS and the dynamic simulation was carried out which provides the maximum values of crossing-obstacle and climbing-slope. The simula- tion results on the pavement adaptability are in good agreement with the test data of the physical prototype test. And the validated dynamical model is available for further analysis and optimization of this kind chassis.%针对类菱形整体底盘通过性，提出了其铰接式底盘。利用ADAMS软件建立类菱形铰接式底盘的动力学模型，通过大量的动力学仿真分析，得出了整车的最大越障高度和最大爬坡度。通过实验样车试验验证了菱形车的爬坡、越障等路面自适应能力和仿真结果。
