摘　　要：介绍了一种小天体着陆器的组成和原理,缓冲器电磁阻尼采用电机能耗制动的方法实现,同时提出基于斩波调阻的方法来实现电磁阻尼系数的调整与优化.使用Pro/E进行三维实体建模,并通过接口将模型导入ADAMS,使用ADAMS与Mat-lab进行联合仿真,在Matlab/Simulink中进行阻尼力的规划,对比了半主动控制和被动控制着陆方式的着陆性能,通过虚拟样机技术为物理样机的设计提供基础.Introduced the composition and principle of small bodies lander. Electromagnetic damping of buffer is realized by motor dynamic braking. Meanwhile, proposed the resistance chopper control method to achieve the adjustment and optimization of electromagnetic damping coefficient. Used Pro/E to make a 3 - D solid modeling, and imported the model into ADAMS through the interface. Used the united ADAMS and Matlab simulation, and planed the damping force through Matlab/ Simulink. Compared the landing performance of the semiactive control and passive control method. Provided a basis for the design of the physical prototype through virtual prototyping technology.
