摘　　要：采用多自由度并联机构作为基体,在原机构原动件处辅以可控弹性阻尼装置,运用反向自适应原理,模拟橡胶,较好地解决了多自由度减振问题。以航行中船舶仪器设备需三维隔振为例,分析了船舶仪器设备的减振要求,采用三自由度或具有冗余四自由度并联机构组合弹性阻尼减振装置,介绍了该减振装置的结构及有关参数的设计方法,理论分析与动态模拟及试验结果一致,说明该减振装置的分析方法是正确的,可推广到其他要求多维减振的设备上。Using parallel mechanisms with controllable dampers on the driving linkages is a possible solution for MDOF vibration damping. Analyzing the instrument vibration damping requirements, a three-dimensional vibration damping system which was based on 3-DOF parallel mechanism or 4 -DOF parallel mechanism with one redundant freedom used for instrument vibration damping on ships was proposed. An inverse-adaptive method was adopted to design the system. The system dynamic performance was analyzed with simulation and experimental methods. The design approach mentioned here may be applied to other MDOF vibration damping system design.
