Abstract

In this study, Passive Earth Pressure of soil mechanics, raised by C.A.Coulomb, is applied to explain the mechanics analysis of wheel vane and then the wheel traction force is developed based on the limit equilibrium theory when a set of vane in the soil. In order to obtain the roughness of lunar terrain and the mechanical vibration characteristics of Lunar Rover, we modelled lunar terrain environment by using 3D solid lunar pavement models constructed by UG, Imageware and ADAMS. Lastly, based on power spectrum curve of lunar terrain environment, the spectral characteristic of lunar terrain with different roughness is educed by using reverse engineering algorithm.
