This paper describes slope traversability analysis for a planetary exploration rover based on a terramechanics approach. In this research, the slope traversability is defined as consisting both of slope climbing and traversing (crossing) capabilities. The authors have been investigated traction mechanics between a wheel of a rover and loose soil. Applying our advantages in the wheel-soil intera...

[1] This paper deals with volume changes of an unsaturated soil in the elastic domain. Two constitutive relations are established in the general framework of unsaturated porous media mechanics. They express the variations of the void ratio e and the water content w with respect to the mean net stress (s pg *) and the suction s. Associated with validated experimental results, these relations giv...

This paper presents a concept for the application of particle swarm optimization in geotechnical engineering. For the calculation of deformations in soil or rock, numerical simulations based on continuum methods are widely used. The material behavior is modeled using constitutive relations that require sets of material parameters to be specified. We present an inverse parameter identification t...
