Abstract: The electromagnetic shunt damping absorber (EMSDA) is developed
based on electromagnetic shunt damping mechanism. The governing equation of
planar vibration system equipped with the EMSDA is derived. An optimization
method is presented to determine the main working parameters of EMSDA on the
basis of the built theoretical model. The objective function minimizing the
response variance of system under white noise excitation is formulated. The
particle swarm optimization algorithm is employed in optimization. The
simulated and experimental studies on vibration control by use of EMSDA are
conducted. The results show that the electromagnetic shunt damping absorber can
attenuate significantly the structural vibration.
