基于多信号模型的计量策略设计与验证

Design and validation of the measurement strategy based on multi-signal model

装备可计量性的理论方法研究对提高装备的计量保障水平具有重要意义。针对国内缺乏装备可计量性模型的现状,提出了可计量性分析设计的多信号模型方法。系统总结了可计量性多信号模型的基本理论,详细介绍了在单超差假设及不考虑组元可靠性、计量时间和费用影响下的超差检查用检定和超差定位用检定操作优选算法以及计量策略制定方法。建立了信号产生系统多信号模型,给出了超差-检定相关性矩阵,分析了信号产生系统的计量检定树,结论与信号产生系统实际检定方法相符,实例证明,此方法合理有效。

Theory and method research of equipment measurability is very important for improving the metrology support ability of equipment. Aiming at the lack of equipment measurability model inland, the multi-signal model method is presented for the measurability analysis and design. The basic theory of the measurability multi-signal model was summarized systematically, the optimum seeking method of the out-of-tolerance detection and position, and the design method of measure strategy were introduced in detail on the single out-of-tolerance assumption, without considering component reliability, measurement time and cost implications. The multi-signal model of self-developed signal produce system was established, the correlation matrix was given and the verification tree was analyzed. The conclusions agree with the actual verification method of signal produce system, which proves that the measure strategy is reasonable and effective.
