Locomotion Energy Requirements for Lunar Surface Vehicles 660149
This paper outlines an approach used for determining locomotion energy requirements for lunar surface vehicles. Both analytical and experimental techniques are discussed based on methods developed for the mechanics of terrain-vehicle systems. Factors affecting energy requirements are considered, including motion resistance, vehicle speed, slip, and mechanical efficiency.
Motion resistance factors discussed include grade, inertia, rolling, soft soil, and obstacle resistance. Special attention is given to energy expended due to surface roughness. Some experimental results are presented to verify the soundness of the approach.
