质心测量对于空间飞行器至关重要,新型武器的研制对质心测量精度的要求不断提高.将传统的天平原理与旋转轴结合,利用传感器技术,设计了一种新型质心测量机构,提出了一种能够明显提高质心测量精度的测量方法.描述了具体测量机构的主体结构,给出了机构的测量原理、测量方法,并进行了机构对于质心测量的误差分析.结合测量设备研制,进行了误差估算,理论估算的结果最大误差为0.023 mm.采用标准样件的方法进行了实验验证,具体测量数据显示,最大误差为0.020 mm.结果表明此测量方法理论分析计算与实验结果具有较好的一致性,并达到了较高的测量精度.已采用该方法成功地研制出系列高精度测量设备,配用于相关领域.

The measurement of centroid is very important for aircrafts, and higher measurement preci-sion is needed for the development of new weapons. With the combination of rotational axis, tradition-al balance and sensor technology, a new measurement mechanism of centroid was designed and a new measurement method was put forward, which can improve the measurement accuracy obviously. The structure, the measurement principle and method were presented and the measurement error was also analyzed theoretically, in which the maximum error of theoretical estimating is 0.023 mm for the de-veloped mechanism. The actual maximum measurement error for a standard sample is 0.02 mm, which is very close to the theoretical value. The experimented results show that the measurement pre-cision of this mechanism is very high. Using the mechanism and method proposed, a series of measure-ment equipments were developed and used in related fields.
