    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 transducer and machine vision measure method were employed in experiment demarcating and verifying system to measure force and displacement. The interferential error between experiment result and simulation result for terrain trafficability is less than 5%, so the system is feasible.
