摘要

结合工程实践中的传感器安装固定方式,通过理论模型论证了检波器附加质量、接地弹性支撑系数、检波器尾锥长度等给检波器的幅频特性或相频特性带来的改造或歪曲;通过原位测试实验数据,系统分析获得的振动记录,从实验上证实了理论模型分析结果的正确性.
In combination with the installing style of sensors in practical projects, the influences of the additional mass, the grounding elastic support coefficient, and the tail length of sensors on their amplitude-frequency characteristic and phase-frequency characteristic were demonstrated with the theoretical model. Based on the field test data, the vibration records were systematically analyzed, and the correctness of the result of analysis by the theoretical model was verified.
