the evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. the rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. in the current study, the mentioned phenomen...

The development of mathematical models for describing the dynamic behaviours of fluid conveying pipes, micro-pipes and nanotubes under the influence of some thermo-mechanical parameters results into nonlinear equations that are very difficult to solve analytically. In cases where the exact analytical solutions are presented either in implicit or explicit forms, high skills and rigorous mathemat...

Fluid-induced vibration detection technology for the multiphase sink vortex can help achieve efficient, safe, and low-carbon sustainable industrial production in various areas such as marine, aerospace, metallurgy industries. This paper systematically describes basic principles research status light of important issues related to this recent years. The primary that occur practical application a...

A wear-ring is an important part of the centrifugal pump. The leakage flow in clearance and main at impeller inlet form crossed mixed flows perpendicular to each other. Large eddies shocks are produced intersection two due great velocity difference different directions, resulting losses, unsteady flow, even flow-induced vibration. Consequently, pump performance, pressure pulsation vibration, ot...

Vortex-induced vibration (VIV) is a highly nonlinear fluid-structure interaction (FSI) phenomenon, and its accurate prediction remains challenging. In this study, we developed high-order partitioned FSI framework towards simulation of the VIV phenomenon. The focus on simulating two-way coupled between flexibly mounted rigid body surrounding fluids. framework, computational fluid dynamics method...

background many industrial devices have an excessive vibration which can affect human body systems. the effect of vibration on cochlear histology has been as a debatable problem in occupational health and medicine. objectives due to limitation present in human studies, the research was conducted to survey the influence of vibration on cochlear histology in an animal model. materials and methods...
