The Calibration Method of the Distortion Spectrum of Aircraft DC Power Supply Characteristic Testing System

通过对飞机直流供电特性测试系统校准装置的畸变频谱信号产生原理进行介绍,并依据JJF 1059.1-2012《测量不确定度评定与表示》对飞机直流供电特性测试系统校准装置直流电压畸变频谱进行不确定度来源分析,给出了直流电压畸变频谱不确定度的具体评价方法。最终,按照上述不确定度评价方法对飞机直流供电特性测试系统校准装置直流电压畸变频谱不确定度进行了评定。

In this paper,the principle of distortion spectrum signal generation of the calibration device for the aircraft DC power supply characteristic testing system is introduced. According to JJF 1059-1999 ＂ Measurement Uncertainty Evaluation and Representation＂,the uncertainty sources evaluation of DC voltage distortion spectrum calibration system of DC power supply characteristic calibration device were carried out,and the uncertainty evaluation method was given. Finally,according to the above-mentioned uncertainty evaluation method,the calibration uncertainty of DC voltage distortion spectrum of the DC power supply characteristic calibration device was evaluated.
