确定自旋航天器旋转轴的动平衡方法

本文研究自旋航天器的旋转轴的试验测定方法，给出自旋轴方向的表示方法及其与转动惯量，惯性积的关系，建立了利用动平衡试验的不平衡量确定自旋轴相对平衡旋转轴偏差的计算机公式，从而可以利用动平衡试验的测试结果确定自自旋轴的方向，文末的例中讨论了动平衡机的最小可达剩余不平衡量对试验结果的影响。

A Dynamic Balancing Method for Determining the Axis of Rotation of Spinning Spacecraft

In this paper the experimental methods to measure the axis of rotation of spinning spacecrafts are investigated. The expressing forms of direction of sPinning axis and their relations with the moments of inertia and products of inertia of spacecraft are given. The calculating formulas for determiningthe relative deflections between the spinning axis and axis of rotation in dynamic balancing test using theunbalances of correction planes which are obtained by the dynamic balancing test are set up. There fore,the direction of spinning axis may be obtained by the measured results of balancing machine with two correction planes. In the example, the influences of the minimum achievable unbalances of balancing machinefor the experimental results are discussed.
