【摘要】：作为低温风洞测力试验的核心测试设备,低温天平受低温风洞气流温度低、温度变化大的影响,会产生零点温度漂移、灵敏度变化等一系列问题,对试验数据的精准度产生影响。因此,相较常温天平而言,低温天平的研制要求更多,难度也更大。在广泛调研国外低温天平研究进展与关键技术的基础上,系统介绍了低温天平的设计与优化、天平材料的选取及热处理、天平的加工与制造、天平应变片的匹配及粘贴、天平校准方法及校准设备等天平研制的多个关键环节,并对未来低温天平技术的发展进行了展望,为我国低温天平的研制及工程化应用提供参考。
[Abstract]:As the core test equipment of low temperature wind tunnel force test, low temperature balance is affected by low air temperature and great change of temperature in low temperature wind tunnel, which will produce a series of problems such as 00:00 temperature drift, sensitivity change and so on. Therefore, compared with the normal temperature balance, the development of low temperature balance is more demanding and more difficult. On the basis of extensive research on the research progress and key technology of foreign low temperature balance. The design and optimization of low temperature balance, the selection of balance material and heat treatment, the processing and manufacture of balance, the matching and sticking of balance strain gauge are introduced systematically. The calibration method and calibration equipment of balance are discussed in this paper. The future development of low temperature balance technology is prospected, which provides a reference for the development and engineering application of low temperature balance in China.
