Chassis design of a new type of lunar rover with a dual rocker-bogie and torsion bar

A design method for a lunar rover which must perform tasks while exploring a region was developed, and parameters used when selecting the lunar rover's chassis were introduced. Traction performance of lunar rovers is determined by thrust available from the soil and resistance to motion, both of which are determined by the nature of the soil and the configuration of the rover. From the point of view of traction performance, conceptual principles of chassis design were developed. Classic terramechanics and vehicle design were utilized to construct a conceptual design method for the chassis of lunar rovers. A new type of lunar rover chassis was then proposed and analyzed. Through simulation of this chassis, it was verified that this chassis can satisfy performance requirements, and that the concepts behind the design method are rational and valid.
