Efficiency of a Three-Particle Energy Sink: Experimental Study and Numerical Simulation
2018, Vol. 14, no. 3, pp. 355-366
Abstract
The results of an experimental and numerical investigation of the dynamics of a string
with three uniformly distributed discrete masses are presented. This system can be used as
a resonant energy sink for protecting structural elements from the effects of undesirable dynamic
loads over a wide frequency range. Preliminary studies of the nonlinear dynamics of the system
under consideration showed its high energy capacity. In this paper, we present the results of
an experimental study in which a shaker’s table mounted cantilever beam was being protected.
As a result, the efficiency of the sink was confirmed, and data were also obtained to refine the
mathematical model. It was shown that the experimental data obtained are in good agreement
with the results of computer simulation.
