A manned pressurized lunar rover is expected to expand the range and the duration of the manned lunar exploration. The dynamic motion of the rover may be different from that on the Earth because such a heavy rover (several tons) travels on loose soil under the low gravity of the moon. Therefore, the main scope of this study is to analyze the dynamic motion of the pressurized rover using a multibody dynamic simulator. In particular, we focus on the steering maneuverability of the rover with regard to vehicle design parameters such as the vehicle tread, wheelbase, and position of the center of gravity. The steering maneuverability of the rover is evaluated based on the wheel slip angle and vehicle rollover stability. The simulation study clarified that the wider tread and lower position of the center of gravity improve the steering maneuverability. Based on the simulation results with different vehicle design parameters and steering input, we summarize allowable vehicle design parameters for improving the steering maneuverability.
