Analysis on Mechanical Parameters of Lunar Rover Wheel
نویسندگان
چکیده
In order to study passing ability of lunar rover in lunar soil, the mechanical parameters between lunar wheel and lunar soil should be analyzed. The mechanical parameters can reflect the mechanical relationship between lunar rover wheel and regolith. These parameters include sinkage, drawbar pull, driving torque, motion resistance and slip. In this paper, these parameters are measured by soil bin test. The results show that, the four parameters increase with slip and loading, except motion resistance of the test wheel which is under 70N at the speed of 25mm/s. The variations of the four parameters are slightly influenced by velocity.

Terramechanics-based model for steering maneuver of planetary exploration rovers on loose soil
This paper presents analytical models to investigate the steering maneuvers of planetary exploration rovers on loose soil. The models are based on wheel-soil interaction mechanics, or terramechanics, with which the traction and disturbance forces of a wheel are evaluated for various slip conditions. These traction forces are decomposed into the longitudinal and lateral directions of the wheel. ...

متن کاملTerramechanics-based Analysis and Control for Lunar/Planetary Exploration Robots
Surface mobility using wheeled mobile robots (Rovers) is one of the important technologies for lunar/planetary exploration missions. The rover in these missions significantly expands the exploration area and thus increases the scientific or programmatic return from the mission. These planetary exploration rovers are expected to travel long distances and perform complex tasks in order to fulfill...
متن کاملStudy on grouser mechanism to directly detect sinkage of wheel during traversing loose soil for lunar exploration rovers
The rovers, which some researchers and agencies are developing, have many functions to sense a lot of information from peculiar environments like the lunar surface for localization, path planning and so on. On rough terrain, without artificial ground maintenance, like the lunar surface, the rovers avoid obstacles by using sensors, which they have. However, if the rovers traverse loose soil, lik...
