Aimed at the demand of docking and sample transfer simulation platform on the ground serving third phase of a three-step moon motion, 12-DOF Space Simulator flotation simulation platform is designed. A new time-optimal trajectory planning algorithm is proposed based on kinematic constraints. The virtual Pro-totype is constructed in SolidWorks and Labview. Optimal trajectories and design parameters are obtained at the advantage of flexible and reusability of virtual simulation platform. Lastly, Deploying joint simulation program to actual simulation platform, the results show that angle error can be controlled within ± 0. 004° and angular velocity error is less than ± 0. 015°/s ,what meets actual engineering requirements.
