摘　　要：在减振装置中采用六自由度并联机构作为基体,在原动件处辅以可控弹簧阻尼系统,较好地解决了多自由度减振问题,克服了橡胶容易老化的特点。以航行中船舶仪器及乘客需隔振为例,分析其隔振要求。进行了位置反解分析与实例验证,并用ADAMS软件对此装置主体机构进行了运动学仿真分析、减振仿真分析,表明其减振效果明显。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.
