A method of topology synthesis based on graph theory and mechanism combination theory was applied to the configuration design of locomotion systems of lunar exploration rovers (LER). Through topology combination of wheel structural unit, suspension unit, and connecting device unit between suspension and load platform, some new locomotion system configurations were proposed and the metrics and indexes...
In order to analyze the performance of lunar rover, draw bar pull and motion resistance are analyzed in this paper based on terramechanics. The relationships between configuration parameters (like wheel width, wheel bases et al.) and mobility performance parameters are obtained from the analysis. Meanwhile, the sensitive factors of the motion resistance are found. Then main performance evaluation...
