    Abstract
  • The asteroid landing mechanism is used to landing on the asteroid. Its landing dynamic and landing performance studies have a grateful guidance to the design of itself. The mechanical characteristics and landing strategy of the small landing mechanism with three legs were analyzed, and then a Lagrange method was introduced to build its two-dimensional landing dynamic model. This model described the dynamic characteristics of the landing mechanism in the landing and turning stages. The analyzing results of this model were validated by simulation. Their results were close and had accordant changing trends. On the most permitted inclined landing slope with 30 degree, the landing performance of the landing mechanism with different landing velocities and yaw angels were simulated in Adams software and analyzed statistically. The results show that the landing mechanism has a reasonable landing performance.
