摘　　要：为了达到侧壁悬挂式雷达多维隔振的目的,提出一种基于并联机构的隔振平台。该隔振平台隔振杆采用具有拉压双向隔振性能的隔振器,满足侧壁式悬挂隔振要求,且具有6自由度多维隔振功能,利用ADAMS软件对隔振平台进行正弦扫频和半正弦波冲击仿真,验证平台具有多维隔振和防冲击性能;最后完成原理样机制造,并在振动台上对原理样机进行正弦扫频和半正弦波冲击实验,对比仿真和实验数据可以发现,仿真模型与实验模型具有较好的一致性,该隔振平台具有良好的减振性能,对侧壁悬挂式雷达具有很好的保护作用。In order to isolate multi-dimension vibration of the radars suspended on the side wall,a kind of multi-DOF isolation platforms based on parallel-connection mechanism is proposed.The platform has a two-way isolation rod which can work under both tension and compression states for the requirement that the whole platform must be suspended on the wall vertically.The isolation function and anti-shock performance of the platform are simulated under sinusoidal excitation and semi-sinusoidal wave impact excitation using ADAMS software.The prototype of the platform is manufactured and tested on a vibration test table under the load of sinusoidal sweeping and semi-sinusoidal wave impact.The simulation result and the experimental result are compared mutually and found to be in good agreement.It is concluded that the platform has good vibration damping performances for protecting suspended radars effectively.
