Abstract

Based on the ship vibration motion characteristics, in this paper, it has put forward a new kind of 3 rotations and 2 translations five degrees of freedom parallel mechanism, the 4-CPS/RPS, which suites for shipboard active vibration isolation. The inverse kinematic solution of the 4-CPS/RPS is obtained, the dynamics model is established by using Lagrange method; Then the wave model and ship motion gestures are simulated, the PID control and the force-position redundant control are further researched; finally the Adams-Simulink joint simulation is used to verify the correctness of the PID control and the force-position redundant control.
