| 中文摘要: |
| 受试验现场诸多因素的影响，多维力传感器实验室校准系数已不适用于液体火箭发动机试验现场测试使用。针对液体火箭发动机多维力测量装置开展现场原位校准方法研究，对真空环境干扰、管路约束力以及温漂等影响因素进行了分析。结果表明，该方法能有效降低多维力测量装置的不确定度，为多维力测量领域的现场校原位准提供了参考。 |
| 英文摘要: |
| Due to many factors in the test site, the calibration coefficient of multi-dimensional force sensor in laboratory has not been applied to the liquid rocket engine test site. The in-situ calibration method for the liquid rocket engine multi-dimensional force measurement device is studied in the paper. The influence factors of vacuum environment, pipeline binding force and temperature drift are also analyzed. The results show that the calibration method can effectively reduce the uncertainty of the multi-dimensional force measuring device, and provide a reference for the in-situ calibration in the field of multi-dimensional force measurement. |
