弹体质偏称重测量法的精度分析

Precision analysis on weight measurement methods of centroidal deviation for ammunition

根据文献介绍的质偏测量方法及计算公式,推导出误差的计算公式.根据误差计算公式给出这两种方法的精度对比,为减少误差,对测试仪器进行了合理的结构分析以及改进方案。指出文献给出的某些结论性意见缺乏理论依据,不宜作为测试方法的选择和精度比较的依据。

According to the literature introduction of calculation formula and measurement methods of centroidal deviation, the accurate error formula was derived. Based on the error formula, the precision contrast of two methods was given. In order to reduce errors, reasonable structure and the improvement plan of the test instrument were put forward. It is pointed out that some conclusions of literature lacks theoretical evidence, should not use as the choice of test method and the basis of precision contrast.
