Landing performance simulation of an asteroid landing mechanism

Asteroid landing is a new research field in deep space exploration, which has important scientific and economic values in learning the origin of the solar system and exploring the asteroid. It is microgravity and little media properties are obtained on the asteroid surface, thus good landing performance is demanded to realize safe landing of the landing mechanism. Landing mechanism in the paper has three legs, and the damping device is located between the landing gear and the equipment base. Simulation method is introduced to analyze the landing performance of the landing mechanism. Landing performance of the landing mechanism on 30° landing slope with the largest landing velocity is simulated in three typical landing modes, and the landing performance is reflected by stability time of the landing gear and overloading acceleration of the equipment base. Landing simulation has important significance in learning landing performance and guiding the landing of the landing mechanism.
