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。传感器在保证试验数据的准确性中起到了决定性的作用。主要从传感器的安装方法、安装角度以及控制点选择等方面进行了分析。正确的传感器固定方式可使系统静态噪声从0.105 mV降至0.019 mV。在试验中,传感器的单点控制会导致探测器的一些频率点数据放大22.9倍。通过多点控制研究与应用将振动量级控制在1.007倍,有效保证了振动试验的准确性。
Abstract
The concept,purpose as well as the components of vibration test are introduced,and a brief description of various tests is given. In addition, the weaknesses of infrared detector which can be examined by vibration test are elaborated. The sensors play a decisive role in ensuring the accuracy of test data. The installation method,installation angle and the control point selection of the sensors are mainly analyzed. The correct fixation mode of the sensor can reduce the static noise of the system from 0.105 mV to 0.019 mV. In the test, the single-point control of the sensor will lead to the amplification of some frequency point data of the detector by 22.9 times. The research and application of multi-point control can control the magnitude of vibration at 1.007 times, effectively ensuring the accuracy of the vibration test.
