Experimental validation of impact energy scattering as concept for mitigating resonant vibrations

Autor: Malte Krack, Timo Theurich

Publikováno v: Journal of Structural Dynamics.

The Vibro-Impact Nonlinear Energy Sink (or impact damper) is well-known for its ability to engage into transient resonance captures with arbitrary frequencies and thus has inherent broad-band effectiveness. Its working principle relies on (recurrent)

Computational and experimental analysis of the impact of a sphere on a beam and the resulting modal energy distribution

Autor: Felix Gehr, Timo Theurich, Carlo Monjaraz-Tec, Johann Gross, Stefan Schwarz, Andreas Hartung, Malte Krack

We consider the common problem setting of an elastic sphere impacting on a flexible beam. In contrast to previous studies, we analyze the modal energy distribution induced by the impact, having in mind the particular application of impact vibration a

Predictive design of impact absorbers for mitigating resonances of flexible structures using a semi-analytical approach

Autor: Malte Krack, Alexander F. Vakakis, Timo Theurich

Analytical conditions are available for the optimum design of impact absorbers for the case where the host structure is well described as rigid body. Accordingly, the analysis relies on the assumption that the impacts cause immediate dissipation in t

Effects of modal energy scattering and friction on the resonance mitigation with an impact absorber

Autor: Timo Theurich, Malte Krack, Johann Gross

A linear vibration absorber can be tuned to effectively suppress the resonance of a particular vibration mode. It relies on the targeted energy transfer into the absorber within a narrow and fixed frequency band. Nonlinear energy sinks (NES) have a s

Vibration suppression and modal energy transfers in a linear beam with attached vibro-impact nonlinear energy sinks

Autor: Alexander F. Vakakis, Lawrence A. Bergman, Bin Fang, Malte Krack, Timo Theurich

Publikováno v: Communications in Nonlinear Science and Numerical Simulation. 91:105415

We present a comprehensive study of nonlinear resonant modal energy scattering and passive vibration suppression in a linear cantilever beam with vibro-impact nonlinear energy sinks (VI NESs) attached to it. It is well-known that vibro-impacts are a
