The data presented in this article is in relation to the research article "Vibration energy harvesting based monitoring of an operational bridge undergoing forced vibration and train passage" Cahill et al. (2018) [1]. The article provides data on the full-scale bridge testing using piezoelectric vibration energy harvesters on Pershagen Bridge, Sweden. The bridge is actively excited via a swept ...

Vibration stimulates specific receptors, cutaneous and musculo-tendinous. The aff erent impulses travel through spinal neurons to thalamus and cortical structures. The local muscular response to a vibration is a tonic vibratory refl ex. This refl ex depends on many factors: frequency, amplitude, and tendon and muscle length. Based upon this refl ex, vibration produced alteration of isometric an...

This paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. After a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. Using doublet mechanics, the relation between natural f...

In this paper, guided wave health monitoring in plate structure for detection of nonlinear contact scatter is conduct using vibration modulation technique. By time-frequency analysis of modulated guided wave series, the nonlinear responses at frequency of vibration are extracted out and used for defect imaging. It is shown that the nonlinear guided wave imaging method based on vibration modulat...

Based on the development of numerical analysis techniques over the past decade, the engineer can easily model the internal flow conditions and vibration characteristics of turbomachinery. When focusing on vibration response of rotating blades, it is easy to predict the resonance frequency; however difficulty remains in the prediction of vibrational stress. The primary reasons include: The unste...

Many vibration suppression systems are required to function across a variety of different temperatures, yet most literature ignores the effects of temperature changes on the structure and on the closed loop response. This paper presents an experimental implementation of a vibration suppression system based on a piezoceramic actuator that effectively controls vibration of a clamped panel as it u...
