Abstract
Vibration neutralizers provide an effective method of attenuating tonal vibrations within a structure. In this paper, variable stiffness vibration neutralizers are used to impose zero displacement or nodes to reduce vibration at desired locations on a Euler-Bernoulli beam subjected to forced harmonic excitation. An iterative procedure is developed to find the required resonance frequencies of neutralizers to create nodes at selected locations. Numerical tests are performed to show the viability of the procedure that is developed. Experimental tests are conducted and results are compared with those obtained by numerical tests.
