Research on Torsional Vibration Measurement Based on Doppler Accelerometer

HUANG Zhen, LIU Bin (College of Information Engineering,Yanshan University,Qinhuangdao,Hebei 066004,China)  
A novel method of torsional vibration measurement,based on the laser Doppler accelerometer,is described.Its principle,the mathematical model of the optical configuration,and the feasibility are also presented.The laser beams,with Doppler-frequency-shift,are reflected from 2 points of the same section.With the proper optical configuration,heterodyne the beams of two different times on the photodetector,therefore the angular accelerationis measured directly,so the information of torsional vibration is obtained.Comparing withother methods,the dynamic range of measurement is extendedgreatly.It is essential to monitor the running state and diagnosethe failure of large-scale gyration machinery with high rotational velocity.
