摘要
参照美国军用标准MIL-STD-45662A《校准系统要求》和适航要求中对计量标准的选择原则,从适宜性和经济性两方面阐述了民机制造业中计量标准选择的4倍允差比关系,并举例说明了计量标准选择时允差比的内涵。研究结果表明,计量标准的允差小于等于被校对象允差的四分之一是民机制造业中计量标准选择时其适宜性和经济性的最佳结合点。
Refer to the metrology standard selection principle of U.S.military standard MIL-STD-45662A Calibration System Requirements and airworthiness requirements,this paper describes four times permissible error ratio relationship when metrology standards are selected in civil aircraft manufacturing industry from two aspects of suitability and economy,and illustrates the meaning of permissible error ratio in the metrology standard selection with some examples.The research results show that the permissible error of metrology standard should be less than or equal to a quarter of the permissible error of calibrated object,which is the optimum combined point between the suitability and economy in metrology standard selection of civil aircraft manufacturing industry.
