The invention provides an air floatation rotating device with variable mass inertia, and belongs to the field of ground verification tests and the field of aerospace industry tests. The device comprises a floating rotating table 101, a mounting frame 102 and a base 103, and weights with different masses are arranged at different positions in the floating rotating table 101, so that the overall mass inertia is changed. The rotary floating table is ventilated, then a certain initial force is applied to the floating rotating table 101, so that the whole floating rotating table 101 rotates without friction, and the overall rotating angle and the rotating angular speed can be obtained through the encoder assembly and are used for verifying a rotational inertia calculation method.
本申请提供一种质量惯量可变的气浮旋转装置,属地面验证试验领域与航天工业测试领域。其包括漂浮旋转台101、安装框架102、基座103三部分,通过在漂浮旋转台101内不同位置布置不同质量的砝码,来实现整体质量惯量的改变。给旋转漂浮台通气,再给漂浮旋转台101一定的初始力,使得其整体发生无摩擦转动,通过编码器组件可获取整体的转动角度与转动角速度,用于对转动惯量计算方法进行验证。
