摘　　要：分析了光电侦察吊舱隔振器的作用以及对机载光电吊舱测量精度的影响,提出了一种多框架光电吊舱的隔振措施,该方法通过对振动的分级衰减,可以有效隔离由光电吊舱载体引起的20Hz以上的振动。通过对隔振器的结构设计,使隔振器按照X、Y、Z向平动,不产生转角,解决了隔振和精确测量的矛盾。Analyzed the function of damper to photoelectric turret and the influence of measuring precision to aircraft-borne photoelectric turret.In order to obtain exact measure precision,we adopt a new technique based on multi-frame turret to vi-bration isolation.The technique can effectively isolate above 20Hz vibration which caused by the aerocraft.And,through structural designing,can make the damper move according to X,Y,Z to the stable motion,has no-angle revolving.The technique can solved the contradiction between damper and the precision measuring on turret.
