航空光电吊舱隔振器布局方式分析

航空光电吊舱在军事和民用得到领域广泛应用,具有情报搜集、监视、侦测、森林防火等作用。为保证航空光电吊舱在飞机载体上具有良好的成像质量,必须进行减震设计。通过理论分析得到,增大隔振器的跨距的布局方式可以减小光电吊舱震动过程中的整体摆动对成像质量的影响,之后通过实际产品在不同隔振器安装跨距的情况下的振动试验,并对振动台的实际振动实验数据进行分析对比,得到大跨距的安装方式的成像质量优于小跨距安装方式的结论,为之后的理论设计和实际应用提供借鉴。

Analysis on vibration isolator layout of aerial optical-electronic pod

Aerial optical-electronic pod is widely used in military and civil fields,and has the function of information collection,overlook,detecting,forest fire protection and so on. To ensure better imaging quality of the aerial optical-electronic pod in aircraft,vibration absorber must be designed and used. After analyzing theoretically,conclusion is gotten that when camera is selected,widening the track of the vibration absorber can improve the imaging quality which is influenced by the sway of the aerial optical-electronic pod. After experiment with practical product and analyzing the data,it also gets the same conclusion. It provides support for future theory design and practical application.
