Abstract
The study of time-averaged vibrational power input to flexible beams and rectangular plates subjected to co-located simultaneously sinusoidal force and moment excitations has resulted in various potential vibration control schemes, both active and passive approaches, based on minimization of the resultant vibrational power input to the structures. The theory and analytical results have been presented in the two companion papers. In this paper the experimental arrangements for verification of the theoretical predictions are described. The optimal moment arm concept for the vibration levels by using combined force and moment excitations is validated on beams and rectangular plates experimentally. It is also demonstrated that by using a set of force and moment seating devices with predetermined moment arms, the vibrational response around the fundamental resonance frequency of a supporting rectangular plate caused by unbalance motor excitations can be reduced.
