Abstract
PURPOSE:To enable high precision measurment without error by amplifying an input signal to the measuring instrument of dynamic characteristics and correcting the measured signal by the rate of amplification when the displacement speed of the vibration-proof rubber is lowered to less than the specified value. CONSTITUTION:The dynamic load F due to the vibrator 1 is obtained by means of the load detector 3. When the damping coefficient C and spring constant K are obtained in the block 1 through the displacement X, displacement speed and acceleration of the vibration-proof rubber due to load F, the vibration detecting circuits 12 and 11 are provided to detect amplitude of signals F and X. These circuits have comparative functions to produce the output corresponding to the percentage of decrease in the rated level of operation of Block I, for example, if such decrease is 50% or less. The above output is input to the calculation control circuit 13. According to the instructions, the control circuit 13 switches the gain switch amplifiers 14 and 15 and increases or decreases amplitude of X by known magnification of n.
