MOBILITY EVALUATION AND
INNOVATION OF WHEELED
SPACE ROVER*
Abstract:
The mission and function requirements of lunar rover are analyzed, based on virtual prototype technology, the mobility evaluation theory and method for wheeled space rover are proposed, which provide a new way to study the innovative design of lunar rover. Based on the above theoretical system, an innovative lunar rover suspension system, which adopts a two-crank-slider mechanism, is proposed, and its dynamics model is created. Adopting virtual prototype technology, the ground adaptability, over-obstacle ability and driving placidity of the rover are evaluated in the virtual proto-type software ADAMS. The analysis results show that the rover provides a high degree of mobility.
