【摘要】：航天器用应变片是某系列卫星上用于星箭解锁装置的重要力学测量元件。依据星箭解锁分离包带应变片粘贴工艺规范,总装检验人员需要在粘贴前对应变片进行检查和筛选。鉴于原有筛选测试方法的缺陷,对应变片筛选测试设备进行设计研制。经过对研制设备装调、校准、测试、比对的研究,以及对其进行各通道线路附加电阻、各通道电阻测量一致性两项测试,消除了应变片受压状态不确定因素及手持接线夹连接引线测试状态不稳定的问题,最终在测试可靠性、测试效率、对应变片的保护等方面均优于原有筛选测试方法。
[Abstract]:Strain gauges for spacecrafts are important mechanical measurement elements used in a series of satellites for unlocking satellites. According to the technical specifications for attaching strain gauges in the unlocking separation belt of spacecraft, the strain gauges are used in a series of satellites. In view of the defects of the original screening and testing methods, the strain gauge screening and testing equipment is designed and developed. After the research on the installation, calibration, testing and comparison of the developed equipment, The additional resistance of each channel and the measuring consistency of the resistance of each channel are tested, which eliminates the uncertain factors of the strain gauge compression state and the instability of the testing state of the hand-held wire clamp lead. Finally, the reliability of the test is in progress. The test efficiency and the protection of strain gauge are better than the original screening test method.
