Energy harvesting mechanisms can be used to extract energy from ambient surroundings power small electronic devices, which has a significant advantage in realizing self-sustaining wireless devices. The proposed design of this study uses the internal fluid flow within pipe and takes fluid–structure interaction through flow-induced vibration bluff body. hybrid harvester convert electrical piezoel...

Placing porous media in a water tank can change the dynamic characteristics of sloshing fluid. Its extra damping effect mitigate and, thereby, protect integrity liquefied natural gas tank. In addition, out-of-phase force enables to serve as vibration absorber for floating structures ocean environment. The influence on wave-induced fluid and associated interaction with substructure ambient wave ...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

BACKGROUND/AIM To assess whether osteocytes have an effect on reflex myoelectrical activity during whole-body vibration (WBV) in postmenopausal women. MATERIALS AND METHODS Participants were classified into 2 groups: the low bone mineral density (BMD) group (n = 37) and normal BMD group (n = 43). Hip BMD was measured using dual-energy X-ray absorptiometry. Surface electromyography data record...

Pipe vibration induced by water hammer frequently emerges in conveyance system, especially the hydropower plant or pumped storage power station with long diversion pipelines. This turn affects hydraulic pulsation so that undesired fluid-structure interaction (FSI) arises. In this research, attention is given to a pipeline embedded concrete. A six-equation model was derived describe fluid-pipe-c...

As one of the fundamental problems in fluid mechanics, flow-induced vibration a flexible cylinder helps shed light on various complex fluid–structure interaction phenomena, such as coupling effect cross-flow and in-line motions relationship between external forces vortical wake patterns. This paper devised non-uniform in-flow condition (partially uniform flow partially still water) for cylinder...

The Dynamics characteristic of Tower Crane is complicated under the wind excitation which complicates the wind-induced vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite element method and Virtual Excitation Method. The pulsating wind loads are changed into multiple-point correlation stationary excitation. This papers uses Davenpor...
