Abstract
PURPOSE: To enable to perform dynamic measurement of vibration-proof rubber automatically, by using the weight signal to the vibration-proof rubber and the displacement speed signal and displacement signal of vibration-proof rubber.
CONSTITUTION: If the voltage at point A is delayed by θ to the voltage at point B, the outputs Q, Q' of RS flip flop 15 are pulses of H or L level having the time width corresponding to the angle θ and they are delivered to the JK flip flop 16. When the trailing signal is incoming to the terminal C of the JK flip flop 16 from the wave shape circuit 14, the JK flip flop 16 is inverted to open the NAND gate 18 and close 19. The pulse motor turns forward and the potentiometer Gc is adjusted until the phase difference between the points A and B can be zeroed. If the voltage at point A advances to the voltage at point B, the pulse motor 21 goes reverse and the potentiometer Cc is similarly adjusted. The damping coefficient C is displayed with the display unit 22.
