| 中文摘要:介绍了振动试验的概念、目的以及各个组成部分，并对各种试验作了简单说明。通过振动试验可以检验红外探测器各部分的薄弱环节。为保证试验数据的准确性，其传感器起决定性作用。主要从传感器安装方法、安装角度、控制点选择等方面进行了分析。结果表明，正确的传感器固定方式可将系统静态噪声从0.105 mV下降到0.019mV。试验中传感器单点控制会造成探测器在一些频率点的数据放大22.9倍，而通过多点控制研究应用，可将振动量级控制在1.007倍，有效保证了振动试验的准确性。 |

| Abstract:This paper introduces the concept and purpose of vibration test, as well as the components of vibration test, and gives a brief description of various tests.In order to ensure the accuracy of the test data, the sensor plays a decisive role. The sensor installation method, installation Angle and control point selection are mainly analyzed.The static noise of the system can be reduced from 0.105 mV to 0.019 mV by the correct fixation mode of the sensor.In the test, the single-point control of the sensor will magnify the data of the detector at some frequency points by 22.9 times. Through the research and application of multi-point control, the magnitude of vibration is controlled at 1.007 times, effectively ensuring the accuracy of vibration test. |
