The invention provides a two-stage active vibration isolation pointing satellite platform configuration based on a Stewart voice coil motor, and relates to the field of satellite vibration isolation configuration design, which comprises a satellite platform, a rear-end Stewart voice coil motor, a load rear end, a middle cabin section, a front-end Stewart voice coil motor and a load front end, and is characterized in that the load front end is connected with the middle cabin section of a satellite through the front-end Stewart voice coil motor; the rear end of the load is connected with the satellite platform through the rear-end Stewart voice coil motors, and the number of the rear-end Stewart voice coil motors and the number of the front-end Stewart voice coil motors are respectively six; the load rear end and the load front end achieve vibration isolation of the satellite platform through the rear end Stewart voice coil motor and the front end Stewart voice coil motor respectively, and alignment of the load rear end and the load front end is achieved 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 satellite is simple in structure, can be used in high and low orbit satellites, and is wide in application range.
本发明提供了一种涉及卫星隔振构型设计领域的基于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Stewart音圈电机、载荷后端、中间舱段、前端Stewart音圈电机以及载荷前端,载荷前端通过前端Stewart音圈电机与卫星的中间舱段连接,载荷后端通过后端Stewart音圈电机与卫星平台连接,后端Stewart音圈电机和前端Stewart音圈电机的数量分别为六台;载荷后端和载荷前端分别通过后端Stewart音圈电机和前端Stewart音圈电机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;卫星构型简单,可在高低轨道卫星中使用,适用范围广。
