摘　　要：卫星平台作为有效载荷的载体,在轨运行时,会经历复杂的空间动力学环境。一方面,空间环境会对载荷的姿态运动产生干扰;另一方面,平台工作时的运动部件会对空间高分辨率光学载荷的视轴稳定性产生干扰,导致了空基高分辨率光学对地观测系统的像质退化。为解决此问题,提出一种六自由度主动隔振机构的设计方案并仿真验证了方案的可行性。The satellite platform as the carrier of the payload always goes through complex space dynamic environment when it is in orbit.On the one hand,the space environment would interfere with attitude motion of the load;the other hand,when the platform is on duty,the moving parts will interfere the stability of the visual axis of the high-resolution optical payload,resulting in image quality degradation for the space-based high-resolution optical Earth observation system.To solve this problem,a design of six degrees of freedom active vibration isolation was proposed and the feasibility of the program was initially verified.
