为提高风洞天平校准技术水平和确保校准质量,分析了风洞天平校准设备的计量现状,论证了通过计量测试途径定量考核评定风洞天平校准装置性能水平的必要性;通过分析风洞天平校准装置功能,提出了“附加干扰”、“重复性”“、稳定性”“、校准载荷范围”和“公式系数组成项”考核风洞天平校准装置技术水平和校准能力的5个技术特性以及“直接考核”和“间接评定”2条评定方法研究思路,供风洞天平和计量科研工作者参考。
In order to improve the calibration technology of wind tunnel balance and ensure the quality of calibration, the measurement status of wind tunnel balance calibration equipment is analyzed. The necessity of quantitative assessment of the performance level of wind tunnel balance calibration device is demonstrated through the measurement test approach. By analyzing wind tunnel balance calibration Device function, proposed “additional interference”, “repeatability”, “stability”, “calibration load range” and “formula coefficient component ” assessment of wind tunnel balance calibration device technology level And calibration capabilities of the five technical characteristics and “direct assessment ” and “indirect assessment ” two assessment method research ideas for wind tunnel balance and measurement research workers reference.
