| Abstract: | 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. |
