Optimization of impact dynamic vibration absorbers in the frequency band

The paper deals with the methods of calculation and optimization of constructions of the impact dynamic vibration absorbers (DVA ) for the elongated structures. An efficient numerical approach based on the theoretical-experimental method is proposed to maximize the minimal damping of modes in a prescribed frequency range for the tuned-mass impact systems. Methods of decomposition and numerical synthesis are considered on the basis of an adaptive schemes. The influence of dynamic vibration absorbers and basic design elastic and damping properties is under discussion. A technique is developed to give the optimal DVA's for the elimination of excessive vibration in sinusoidal forced systems.
