单轴全物理仿真磁浮台

Uniaxial full physical simulation magnetic floating platform

Abstract

The invention discloses a single shaft full-physical emulated maglev stage which is mainly used for processing full-physical emulation for the control system of the spacecraft and other mobiles. The single shaft full-physical emulated maglev stage comprises a structural supporting unit, a bearing unit, an shaft directional maglev unit, a sensor unit, a gap adjusting and controlling unit and shaftsurface unit. The shaft surface unit, the upper sensor, the upper magnet and the rotor potion of the bearing unit are the rotating potion of the maglev stage; the structural supporting unit, the lower sensor, the lower magnet and the stator potion of the bearing unit, gap adjusting unit are the static potion of the maglev stage; the magnetic force generated between the upper magnet and the lower magnet arranged in the shaft directional maglev unit balances the influence by the gravity to the rotating position can rotate without any frictions around the core shaft. As a free rotating stage, the invention overcomes the shortcomings of larger frictions of the general semi-physical emulated mechanical rotating stage, assuring the control system emulated object having the characteristic of automated close loop.
本发明公开了一种单轴全物理仿真磁浮台,主要用于对航天器等运动体的控制系统进行全物理仿真。该单轴全物理仿真磁浮台包括结构支撑单元、轴承单元、轴向磁悬浮单元、传感器单元、间隙调整与控制单元和轴面单元。其中轴面单元、上传感器、上磁体和轴承单元的转子部分作为磁浮台的转动部分,结构支撑单元、下传感器、下磁体和轴承单元的定子部分、间隙调控单元作为磁浮台的静止部分,轴向磁悬浮单元中相对设置的上磁体和下磁体产生磁力来平衡转动部分重力的影响,以使转动部分能绕芯轴无摩擦地旋转。作为一种自由转台,本发明克服了一般的半物理仿真机械转台摩擦力矩大的缺点,并且可以确保控制系统仿真对象具有自主闭环的特点。
