Equivalence of grounded and non-grounded NES tuning and performance in mitigating transient vibrations

Abstract
Nonlinear energy sinks serve as more robust vibration absorbers than linear counterparts. In the literature, the most popular NES is the non-grounded NES (NGNES), a mass connected to a vibrating mechanical system through a highly nonlinear spring. Less known are the grounded NESs (GNES) that are connected to the mechanical system through a weak linear spring and grounded through a highly nonlinear spring. To increase the performance of the NGNESs, its mass may be increased. However, as the NGNES’s mass rests on mechanical system, this NES’s mass is typically limited to a light weight. On the other hand, GNES design is not limited by its mass as it rests on the ground. Furthermore, the weak connecting spring increases the design flexibility compared to the NGNES. In this contribution, it will be shown that tuning and performance prediction of the GNES performance is highly similar as previously discovered for the NGNES while showing there is more design flexibility for the GNES.
