摘要:
根据扭摆法测量转动惯量原理,研制了基于气浮转台的大型转动惯量测量系统,提出了一种可展开式测量臂结构,利用任意轴定理,实现了一次工装就可以测量出飞行体对三个轴的转动惯量和惯性积,从而有效降低了多次安装带来的定位误差,系统采用了气浮转台,消除了扭摆过程中机械摩擦力对扭摆周期的影响。试验结果表明:转动惯量测量的相对误差不大于0.07%,由于采用了展开式测量臂结构,测量效率提高了3倍。
Abstract:
A large measurement system of moment of inertia based on air-hovered turn-table is developed according to the theory of testing moment of inertia using torsion pendulum.A deployable measure arm is presented,which realizes the measurement of flight object’s moment of inertia and product of inertia relative to three axes by using only one process of installation based on the theory of arbitrary axis,so the positioning errors as a result of repetitious installations are reduced effectively.With the introduction of air-hovered turn-table,the influence of friction force on the cycle of torsion pendulum in the process of swing is reduced.The experimental results show that the relative error is limited within 0.07% in measuring moment of inertia.The measuring efficiency is three times as large as the former due to using deployable measure arm.
