| 英文摘要 | There exists an increasing need for Milli-Arc-Seconds (MAS) accuracy pointing measurement for current and future space systems. To meet the 0.100 space pointing measurement accuracy requirements of spacecraft in future, the influence of spacecraft micro-vibration on a 0.100 Space Pointing Measuring Instrument (SPMI) is studied. A Quasi-Zero Stiffness Device (QZSD) with adaptive adjustment and variable stroke was proposed. Then, a series of micro-vibration experiments of the SPMI were carried out. The influence of the micro-vibration generated by Guidance Navigation Control (GNC) attitude control components under different attitudes on the SPMI was analyzed. Point spread function of image motion in micro-vibration was also derived. Further, the changes of image motion under the micro-vibration environment were evaluated by extracting the gray centroid of the images, and the experiment processes and results are deeply discussed. The results show that the firstorder frequency of the QZSD system is 0.114 Hz, and it is induced by a double pendulum system; the image motion of single flywheel spinning reached 0.015 pixels; whilst the image motion reached 0.03 pixels when three flywheels are combined spinning. These latest findings provide a beneficial theoretical and technical support for the development of spacecraft with 0.100 pointing accuracy.(c) 2022 Chinese Society of Aeronautics and Astronautics.
