Impact and particle vibration absorbers optimal design

Keywords: dynamic vibration absorber, particle-based damping system, buffered absorber, optimization, design

The paper contemplates the provision of impact or particle dynamic vibration absorber (DVA). 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 general viscous tuned-mass systems. Methods of
decomposition and numerical synthesis on the basis of adaptive schemes are considered. The influence of
dynamic vibration absorbers and basic design elastic and damping properties is under discussion. Compact
buffered impact absorbers are analysed. One task of this work is to analyse parameters identification of the
dynamic vibration absorber and the basic structure. The work focused on a single degree of order (SDOF)
system which is equivalent to particle DVA. The simulation provides a close agreement with the measurements
over various entire frequency ranges, which means the SDOF is simple yet easy to calculate the
damped motion, compared with the experimental results of particle DVA. Examples of the attachment of
particle DVA’s and elongated element with multi-mass impact DVA’s are offered. The paper contemplates
the provision of the impact multi-mass DVA’s with masses collisions and traction for additional damping.
A technique is developed to give the optimal DVA’s for the elimination of excessive vibration in harmonic
and impact loaded systems.
