Dynamical and structural systems are susceptible to sudden excitations and loadings such
as wind gusts, blasts, earthquakes, and others which may cause destructive vibration …

Nonlinear energy sink (NES) has received extensive attention as a broadband vibration
control strategy. Generally, the vibration of the NES vibrator is unconstrained. Moreover, the …

Vibration control has been of great interest to scientists and engineers for many years.
Although linear vibration absorbers have been shown to be effective in mitigating vibrations …

Torsional vibration of a gear-shafting system attaching a nonlinear energy sink (NES) is
examined herein. Firstly, a gear-shafting system with two shafts is introduced and then …

A nonlinear dynamic model of nose landing gear (NLG) shimmy considering the coupling of
time-varying load and Coulomb friction is proposed, and the effects of Coulomb friction on …

Accurate shimmy prediction and effective oscillation suppression are essential for aircraft
design as shimmy oscillation remains a significant concern in landing gear dynamics. In this …

Shimmy is described as a self-induced oscillation for the landing gear which is a threat to the
handing quality and safety of aircraft taxiing on the ground. This paper proposes a novel …

Shimmy motion may occur for an aircraft nose landing gear (NLG) during its takeoff, landing,
and taxiing procedure, which is an undesirable motion and should be suppressed. Here, a …

Two major concerns with the nonlinear energy sink (NES) when used as a passive vibration
absorber are the mass of the NES and the threshold of external excitation to initiate the …

Shimmy vibration is a common oscillation in the nose landing gear (NLG) during aircraft
landing and taxiing process, which is a potentially dangerous phenomenon. Herein, the …
