【摘要】 文章主要从文献调研的角度,介绍了应力波天平测力技术的基本原理,对应力波天平的设计、校准、数据处理、风洞试验等方面的研究情况作了较为详细的介绍,并简要介绍了我部开展的应力波天平相关情况。在应力波天平的设计中,建模技术广为使用,保护罩的设计对天平测试性能影响较大。应力波天平的校准方式多样如水平校准、垂直校准、力锤敲击校准都用得很好。通过文献调研和前期试验积累,我们认为应力波天平适合于激波风洞、膨胀管风洞等脉冲型风洞的气动力测量,有必要在国内开展相关技术研究。更多还原

【Abstract】 This paper mainly introduces the stress wave force balance technique,mainly the principle,the balance design,calibration, data processing and wind tunnel tests,also introduces the development of stress wave balance in our institute.During the design, aerodynamic modelling and finite element modelling are used.The shielding is important to the testing results.Various calibrations are used,such as horizontal calibration,vertical calibration and pulse calibration.Through reference investigation and previous research,we think that the stress wave balance fits impulse wind tunnel such as shock and expansion tunnel,it is necessary to carry through correlative.更多还原
