Abstract
PURPOSE: To make it possible to perform the vibrating test safely to a response allowable limit wthout damaging a test piece by providing a level feed-back controller to control the vibrating level by the interactions between respective channels.
CONSTITUTION: A test piece 1 is placed upon a vibrating table 2 and is vibrated by a vibrator 3 so that the vibration level of the test piece 1 is controlled by a level controller 5 in accordance with the quantity of state of multiple dimensions more than two channels measured. The quantities of state thus measured are fed through a gain controller 12 and a DC-AC converter 14 to a level feedback controller 16. The control input to the level controller 5 is controlled so that the responsive level of the test piece 1 falls within the allowable level, which is higher than the disturbances and lower than the allowable limit of the test piece 1, at the measuring point of each channel in accordance with the amplitude between the channels.
