Abstract :
Based on the analysis of the 6-dimension additional motions of ships, a 3-SRR/SRU 3-DOF parallel mechanism is designed as the stabilization platform for the equipment on ships. Firstly, the mechanism structure of the stabilization platform is given and the kinematic equations are formulated. Secondly, a virtual prototyping model of the parallel stabilization platform is established in Adams, and then the kinematic characteristics of the model is verified. According to the kinematic characteristics, the motion control strategy of the stabilization platform is determined. Finally, the PID controller is implemented on a 3-DOF parallel stabilization platform, and the real-time tracking control of the moving platform is simulated.
