摘　　要：为减小振动对光电吊舱成像质量的影响,依据多自由度系统模型理论、隔振理论和实际振动环境设计了小型光电吊舱被动隔振系统,该隔振系统能够合理的配置光电吊舱隔振系统的各阶频率。基于多自由度系统模型理论对隔振系统的各阶固有频率进行配置,指导隔振器的空间布局及相对位置、隔振器的三向刚度及阻尼值和隔震系统支架结构的设计。通过Adams/Vibration模块进行仿真分析,利用振动台对光电吊舱隔振系统进行验证试验,结果显示理论计算、仿真分析和振动试验获得的隔振系统各阶固有频率接近,最大误差不超过10%,且在激振力频率92.5 Hz附近隔振效果明显。外场试飞试验也验证了小型光电吊舱隔振系统的隔振性能。To reduce the airborne vibration influence of airborne optoelectronic pod on quality,a small optical pod antivibration isolation system was designed according to multi-degree-of-freedom system vibration theory,vibration isolation theory and current vibration environment. This vibration isolation system can configure optical pod isolation system natural frequency effectively. The natural frequency of the isolation system was determined through multi-degree-of-freedom system vibration theory,instruct the design of spatial layout and relative positions,damping values and stiffness of isolators,and support structure. The simulation analysis of optical pod isolation system was conducted by using ADAMS/Vibration code module,the optical pod isolation system was tested on a vibration table,the experiment results of natural frequency were consistent with theoretical and simulation results,the error is less than 10%,and the isolation system has good vibration isolation performance near 92 Hz. The field test image effects also prove the damping effectiveness of small optical pod anti-vibration isolation system.
