In petrochemical, marine, and other fields, high-concentration solid-liquid two-phase flow induced pipe vibration has always been a problem worthy of attention. Especially when the oil transports flow, researchers have introduced equivalent density into fluid momentum equation to consider influence on pipes with vibrations. This method ignores particle collision accumulation in vibration, which...

This study proposes a novel reduced-order model (ROM), based on the Volterra series, for aerodynamic force of bridge deck section. Moreover, ROM streamlined box girder section Great Belt East Bridge (GBEB) is identified with computational fluid dynamic (CFD) simulations. Furthermore, an analysis method combining and Newmark-β integration established to simulate aeroelastic responses Finally, wi...

This study concerns a monitoring technique based on vibration measurements for identifying the presence of an acoustic source in fluid-filled pipe conveying turbulent flow. In such situation, source-induced vibrations can be smeared with flow-induced vibrations, which hinders detection. To increase signal-to-noise ratio (SNR), beamforming techniques applied to measured by array accelerometers m...

The development of control systems for a two degreeof-freedom vibration suppression system using a magnetorheological (MR) fluid damper is the subject of this paper. It is assumed that system encounters impulsive disturbance forces. The objective is to use the (MR) fluid damper for the position control and vibration suppression of the payload. The control force is generated by regulating the el...

like most limestone mines, which produce the raw materials required for cement companies, the transportation cost of the raw materials used in the shahrood cement company is high. it has been tried to build the crushing and grinding plant close to the mine as much as possible. on the other hand, blasting has harmful effects, and the impacts of blast-induced damages on the sensitive machinery, e...

Vibration-based flow energy harvesting enables robust, in-situ extraction for low-power applications, such as distributed sensor networks. Fluid-structure instabilities dictate a harvester's viability since the structural response to determines its power output. Previous work on flextensional-based harvester demonstrated that an elastic member within converging-diverging channel is susceptible ...

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...
