A Method for Traction Ability Research of a Rover Wheel on Mixed Planet Terrain with Movable Stones
Space: Science & Technology, 2023 The mixed terrains of terramechanics research are mainly composed of static stones and loose soil. The movement behavior of stones is often ignored while analyzing the influence of the wheel’s traction performance caused by mixed terrain. When a wheel is

Evaluation of the shear deformation model in the process of wheel sinking by the wheel experiment
Nihon Kikai Gakkai ronbunshu, 2015 Soft soils cover on planetary surfaces, so the wheels for exploration rovers easily slip. Understanding an interaction between a wheel and soft soils is important for a traction control to improve rover traversability.
