摘要
载荷隔振装置是为适应高分辨率卫星光学有效载荷高精度、高稳定度工作环境要求而设计的一种高精高稳结构,如何对其特性进行有效的地面试验验证,并量化评估其减隔振效果,成为亟待解决的问题。基于此,通过设计并搭建了一套微振动试验系统,实现了载荷隔振装置的模态特性和传递率特性的测试,获得了有效测试数据,并通过对比分析,量化得到了载荷隔振装置的减隔振效果。试验结果为载荷隔振装置研制提供了重要的基础数据和工程经验,对卫星减隔振系统设计具有广泛的参考价值。
Payload isolation device is a new design structure of high precision and high stability,which is adapting for the high resolution satellite optical payload with high precision and high stability working environment.It is an urgent problem to be solved that how to validate its characteristic effectively by ground test and quantitatively evaluate its vibration isolation effect.In order to test the modal characteristic and transmissibility characteristic of payload isolation device,a set of micro-vibration experiment system is designed and built,through which effective test data can be obtained.Through comparison and analysis,the vibration isolation effect of payload isolation device is quantified.The experimental investigation result provides important basic data and valuable engineering experience for the development of payload isolation device,and provides a wide range of reference value for the vibration isolation system design of satellite.
