Abstract:

This article presents a technique for adapting current modal testing procedures to shaker table tests commonly used for qualification tests of nuclear and space related equipment. It involves a modification of the measured frequency response function of the total acceleration, in order to make the assumptions of the modal testing systems applicable to this type of tests. Experimental results on a simple structure are given and demonstrate the simplicity and applicability of this method.
