Abstract
Research work is conducted on performance evaluation of rover/rover wheel mobility in terms of slip ratio and motion resistance, which helps in solving and to overcome the present existing problems on a deformable soil terrain (flat/sloppy). The aim of this paper is to analyze the slip ratio and motion resistance of rigid wheels with various diameters, widths, lug height and different number of lugs, travelling on TRI-1 or Tiruchirappalli – 1 Lunar Soil Simulant. Slip ratio has more impact on the traveling performance of planetary rover which is a trafficability parameter. Hence, trafficability studies are required to understand –its affects, variation, and improvement of mobility from its parameter’s behavior. This paper brings out a best suitable combination of wheel that travels on TRI-1 Simulant, i.e., lugged wheels (small and large) with lug height 15 mm with 16 number of lugs and both wheels (plain small and plain large) are most suitable on Tiruchirappalli – 1 Lunar Soil Simulant with its maximum travelling performance and better mobility within the cases examined.
