| 旋翼天平原位校准中，校准不确定度是最核心的技术指标。根据实际工况环境，研究了原位校准方法，研制了原位校准装置，重点介绍了机械设计结构，梳理和明确了不确定度来源，最后完成了旋翼天平的首次原位校准测试工作，并依照规范的方法进行了原位校准不确定度评价，结果表明：校准装置性能达标，各力值分量相对校准不确定度均优于0.1%，各力矩分量相对校准不确定度均优于0.3%。 |
| 英文摘要: |
| In the in-situ calibration of rotor balance, the calibration uncertainty is the most important technical factor. First, the environment according to the actual working condition and in-situ calibration method is studied. Then, the in-situ calibration device was developed, mainly introducing the mechanical structure design and ascertaining the sources of uncertainty. Finally, for the first time in-situ calibration test of the rotor balance was completed and for in-situ calibration uncertainty was evaluated in accordance with the standard method. The results showed that the standard calibration device has achieved that the relative force-component calibrating uncertainty is better than 0.1%, the relative torque component calibrating uncertainty is better than 0.3%. |
