The invention provides a two-stage active vibration isolation pointing satellite platform configuration based on a magnetic levitation actuator and a Stewart voice coil motor, and relates to the field of satellite vibration isolation configuration design. The two-stage active vibration isolation pointing satellite platform configuration comprises a satellite platform, a rear-end active vibration isolator, a load rear end, a middle cabin section, a front-end active vibration isolator and a load front end, the load front end is connected with a middle cabin section of a satellite through front end active vibration isolation, the load rear end is connected with a satellite platform through rear end active vibration isolation, and the load rear end and the load front end achieve vibration isolation on the satellite platform through the rear end active vibration isolation and the front end active vibration isolation respectively. And the alignment of the load rear end and the load front end is realized by adjusting the pointing direction and the position of the load rear end. A quiet working environment can be provided for the front end part and the rear end part of the split type load at the same time, and decoupling control over the loads of the two parts is achieved; the provided satellite is simple in structure, and can be used in high and low orbit satellites, especially in the fields of large optical satellites with high micro-vibration requirements, large satellite scale, complex load and the like.
本发明提供了一种涉及卫星隔振构型设计领域的基于磁浮作动器和Stewart音圈电机的两级主动隔振指向卫星平台构型,包括卫星平台、后端主动隔振、载荷后端、中间舱段、前端主动隔振以及载荷前端,载荷前端通过前端主动隔振与卫星的中间舱段连接,载荷后端通过后端主动隔振与卫星平台连接,载荷后端和载荷前端分别通过后端主动隔振和前端主动隔振实现对卫星平台的振动隔离,并通过调整载荷后端指向和位置实现载荷后端和载荷前端的对准。本发明能够为分体式载荷前端部分和后端部分的同时提供安静的工作环境,实现两部分载荷的解耦控制;提出的卫星构型简单,可在高低轨道卫星中使用,尤其是在微振动要求高、卫星规模大、载荷复杂的大型光学卫星等领域。
