The invention provides a passive vibration isolation layout method for micro-vibration suppression of an optical remote sensing satellite and the satellite, and the method comprises the steps: carrying out the layout of an on-satellite micro-vibration source according to the micro-vibration spectrum and magnitude, and transmitting the micro-vibration magnitude of a bottom plate of a satellite to a layer plate, a side plate and a top plate from the bottom to the top, the transmission attenuation characteristic that the attenuation degree is increased in sequence isolates the influence of micro-vibration of on-satellite moving parts on micro-vibration of remote sensing loads. According to the passive vibration isolation layout method, vibration isolation is achieved through the star structure, a vibration isolation device does not need to be added, interference of micro-vibration of the satellite can be effectively weakened, the vibration reduction effect is remarkable, and technical support is provided for high-precision and high-stability work of the optical remote sensing satellite.

    本发明提供了一种面向光学遥感卫星微振动抑制的被动隔振布局方法和卫星,对星上微振动振源根据微振动频谱与量级进行布局,利用星体底板微振动量级传递至层板、侧板、顶板的量级由下至上依次递减,衰减程度依次增大的传递衰减特性,隔离星上活动部件微振动对遥感载荷微振动的影响。本发明涉及的被动隔振布局方法利用星体结构隔振,无需增加隔振装置,可有效减弱卫星微振动的干扰,减振效果显著,为光学遥感卫星高精度、高稳定工作提供了技术支持。
