Abstract

PURPOSE:To obtain amplitude values proportional to the deviated load of the rotary body without compensation by angular speed by using a secondary analog filter. CONSTITUTION:The vibration of the rotating tubular rotating body 1 is picked up by an accelometer 2 as a vibration applying force F by using the Equation (1). Then the signal sensed by the accelometer 2 is amplified by an amplifier 3. The output characteristic of said amplifier 3 is proportional to the angular speed omega of of the rotary body. The output signal of the amplifier 3 is fed to the secondary analog filter 4 having the characteristic shown by the Equation (2), and only the signal corresponding to the deviated load m is picked up. Namely, if cut off frequency omega0 and frequency f are selected, the amplitude value which is indicated by the output signal of the secondary analog filter 4 and proportional to the deviated value m is obtained regardless of the angular speed of the rotary body 1.
