T_7型检衡车检定测量结果不确定度评定

介绍T7型检衡车的检定环境条件及方法,给出测量不确定度的数学模型。分析检衡车测量重复性的不确定度评定、分辨力的标准不确定度评定、检定轨道衡的上一等级标准器引入的标准不确定度的评定,以及合成不确定度评定、扩展不确定度评定等评定过程。

Evaluating the Uncertainty Degree Of Calibration Measurement Result Gained By T7 Type of Weight Bridge Test Car

The author introduces the environment condition and method on the calibration of T7 type of weight bridge test car,and gives the mathematical model for measuring the uncertainty.The author analyses the evaluation of uncertainty degree of measurement duplication,evaluation of standard uncertainty degree of resolving power,eval-uation of the standard uncertainty degree of the standard equipment used to calibrate weighing-in-motion bridge,and also the process of evaluating the composite uncertainty degree and ...
