| 摘 要： | 为了评价越野车辆的地形通过性,建立了基于虚拟试验场技术的评价系统.基于轮胎内压和轮胎刚度与有效接地面积基本成线性的关系,用试验系数对建立的轮胎粘弹性有限元模型进行了修正.研究了悬架的刚度-阻尼模型,并以多体动力学理论建立了车辆的6自由度动力学模型.以车轮六分力传感器和机器视觉测量方法建立了评价仿真模型的标定和验证硬件平台,并对实车试验与评价系统的仿真结果进行对比.对比结果表明:仿真与试验结果的干涉误差在5%以内,因此,评价系统可信.

| Abstract: | In order to estimate the terrain trafficability of off-road vehicle, an estimating system was constructed based on VPG (virtual proving ground) technology. The linear relations of the pressure, stiffness and the effective contact area of tire were analyzed, and the viscoelasticity model of tire was improved with experiment coefficients. The stiffness and damp model of suspension was studied, and a 6 DOF model of off-road vehicle was established based on multi-body dynamics. Six-dimension wheel force transdu... |
