With controllable vibration damping systems installed at the original linkage and adopted parallel mechanism with six degrees of freedom (DOF) as its basic body, this device could perfectly resolve the problem of multi-DOF vibration damping and could overcome the characteristics of rubber's easily aging. Took instrument equipments and passengers in the navigational ships need vibration isolation as an example, the requirement of vibration isolation was analyzed, the kinematics simulation and vibration damping simulation have been done, and the effect of vibration damping was obvious. Moreover, the design method of related parameters was introduced. The analysis method can be use in other multi-dimension vibration damping devices, so there are theoretical and universal meanings for studying it.
