This paper aims to explore the working mechanism of sandwich-like meta-plates by periodically attaching nonlinear mass-beam-spring resonators for low-frequency wave attenuation. The MBS resonator consists a mass, cantilever beam, and spring provide negative stiffness in transverse vibration resonator; this is tunable changing parameters spring. Considering resonator, energy method applied obtai...

One of the most important factors that affect the pointing of precision payloads and devices in space platforms is the vibration generated due to static and dynamic unbalanced forces of rotary equipments placed in the neighborhood of payload. Generally, such disturbances are of low amplitude, less than 1 kHz, and are termed as ‘micro-vibrations’. Due to low damping in the space structure, these...

This paper reports on an investigation into the feasibility of using active and passive means of vibration control in aerospace structures. In particular, attention is focused on controlling vibration transmission through light weight satellite structures at medium frequencies. The initial structure under test here is a 4.5-meter long satellite boom consisting of 10 identical bays with equilate...

The effects of a heavy travelling load on the soil medium and on the adjacent structures were studied. Five soil profiles were analyzed, three from sites in Southern California and two from well documented sites in Europe. It was found that the material damping in the soil layers does not affect attenuation, but rather radiation damping is the most significant. Four of the Five soil profiles st...

In a single-degree-of-freedom weakly nonlinear oscillator subjected to periodic external excitation, a small-amplitude excitation may produce a relatively large-amplitude response under primary resonance conditions. Jump and hysteresis phenomena that result from saddle-node bifurcations may occur in the steady-state response of the forced nonlinear oscillator. A simple mass-spring-damper vibrat...

Traffic signals and information signs play a vivid role in maintaining safe travel by guiding drivers on highways urban roads. mast arm structures are susceptible to vibrations induced wind loads. Fatigue-induced failure is common these structures. However, it crucial ascertain the functionality of signal support This paper lays foundation for fully computational framework model mitigate wind-i...

This paper introduces the concept of nonlocal Acoustic Black Hole (ABH) metastructure and explores, via numerical analyzes, corresponding vibration attenuation performance. Building on basic ABH metastructure, which is a thin plate waveguide with embedded periodic grids ABHs, this work explores feasibility using intentionally introduced nonlocality to expand dynamic operating range absorbers. T...

This is a theoretical, numerical, and experimental study on the vibration attenuation capability of dynamic response building-like structure using absorber in cantilever flexible beam configuration, taking into account gravitational effects associated with its mass.
