【摘要】 本文基于测量系统不确定度的动态特性,研究了测量系统全寿命过程中的动态精度变化及误差分布模型。针对气动测量仪测量油泵油嘴孔径的实例,采用灰色理论建立了实际测量系统精度损失函数。通过预报估计值和实测数据的比对,验证了灰色理论在测量系统精度损失预报方面的准确性和有效性。更多还原

【Abstract】 On the basis of dynamic characteristic of measurement system uncertainty,the models of the dynamic accuracy and error distribution of measurement systems in the whole life are studied in this paper.The Grey theory is adopted to set up the accuracy loss function of the pore diameter measurement system for the fuel injection jump.The veracity and validity of the theory are validated by the experiment.更多还原
