Research on testing method of resonance frequency of telemetry antenna lifting mechanism

研究设计一套遥测天线升降机构谐振频率的测试方法。经测试,遥测天线升降机构不会与天线发生共振,遥测天线谐振频率约为18Hz,升降机构垂直方向的最低谐振频率为12.82Hz,侧向方向的最低谐振频率为25.64Hz,前后方向的最低谐振频率为38.46Hz。

In this paper,a set of measuring methods for resonant frequency of the lifting mechanism of telemetry antenna is designed.By the test,the lowest resonant frequency of the lifting mechanism in the vertical direction is 12.82Hz,the lowest resonant frequency in the lateral direction is 25.64Hz,and the lowest resonant frequency in the front and rear direction is 38.46Hz.The resonance frequency of the telemetry antenna is about 18Hz,so the telemetry antenna lifting mechanism will not resonate with the antenna.
