摘要：

针对光学遥感卫星面临的微振动对成像质量影响的问题，对微振动抑制设计方法和关键技术进行了论述。首先对动量轮、控制力矩陀螺、扫摆机构等主要扰动源的机理和特征进行分析，然后从传递路径设计、微振动源抑制、降低有效载荷敏感性三个方面介绍了微振动抑制方法，最后结合遥感卫星的研制过程给出了微振动抑制设计的实例。

Abstract:

To avoid micro-vibration induced image quality degradation of optical remote sensing satellite, the design method and key techniques of micro-vibration attenuation are discussed in the present study. First, the mechanism and characteristics of main disturbing sources such as momentum wheels, control momentum gyros, scanning mechanisms are analyzed. Then the micro vibration attenuation methods are introduced in three aspects, i.e. transmission path design, vibration source attenuation, and decrease of the payload sensitivity. Finally, a micro-vibration attenuation design example in the development of a remote sensing satellite is presented.

Key words: Remote sensing satellite, Micro-vibration attenuation, Isolator, Key technique
