摘　　要：针对超静超稳航天器面临的微振动问题进行了研究,提出了一种将微振动诱发指向测量误差和附加力矩误差引入指向测量控制系统的建模仿真方法,基于准零刚度悬吊法对指向测量系统进行了微振动试验。仿真和试验结果表明:微振动诱导的指向测量误差更为显著,峰值到达1×10^(-4)°;微振动引起指向控制系统指向测量误差达到0.03像素;这对超静超稳航天器及其衍生技术研究具有一定借鉴意义。The micro-vibration of ultra-high-static and ultra-high-stable spacecraft was studied.A modeling and simulation method was proposed to introduce the pointing measurement error and additional torque error induced by micro-vibration into the pointing measurement control system.The micro-vibration experiment of the pointing measurement system was carried out based on the quasi-zero stiffness suspension method.The simulation and experimental results show that the pointing measurement error induced by micro-vibration was more significant,and the peak value reached 10e-4°,and the pointing measurement error of the pointing control system caused by micro-vibration was 0.03 pixels.This work can be used for reference in the study of ultra-high-static and ultra-high-stable spacecraft and derivative technologies.
