| 摘 要： | 本文提出了一种利用微波电桥遥测物体振动频率和转速的方法,阐述了测量系统和测量原理。这种方法是利用物体振动时引起测量臂和参考臂的反射波之间的位相差的变化导致电桥失衡来测量振动频率和转速,文中还论证了测量原理中各量之间的定量关系。微波电桥的测量结果与光电转速仪的测量结果对比说明,本装置的测量数据较为可靠。粮据同样原理,可试制出性能优良的测量物体振动和转动的微波仪器。

| Abstract: | A method for measuring vibrant frequency and rotational speedwith microwave bridge isproposed in this paper.The measurement system and the principle are deserubed.This method is developed based on the principle that the bridge is in the state of imbalance caused from the change of difference between the reflective waves when an object is vibrated. The vibrant frequency and rotational speed are measured by using loss equilibriumof bridge.In this paper quantitative relations between the measuring waveshave been derived.A comparason of the results measured by microwave bridgeand the rotational speed meter has been given. |
