Title:
MULTIPLE MODE VIBRATION CONTROL METHOD FOR EXCITATER
Document Type and Number:
Japanese Patent JP3897431
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide the multiple mode vibration control method of an excitater which precisely transmits target excitation input to a structure to be tested/ excited on a large vibration table whose rigidity deteriorates.
SOLUTION: The control method in which the vibration table whose rigidity in the direction of a vibration face is high and which has a peculiar vibration mode in a vertical direction is supported by vertical excitation actuators whose number is more than the number of the highest order of a vibration removable object vibration mode and a computer is provided to execute a control operation based on a concentrated constant-type vibration model 7 containing equivalent quality points M connected by spring constants (k) and the vertical excitation actuators 2 uses as low pass filter operation means, a dumping operation means and an output means, which execute the operation with the signal of a sensor detecting the vibration of the quality point M, and removes the control object vibration mode.
