Test Study on Vortex-Induced Vibration of Deep-Sea Riser under Bidirectional Shear Flow

Journal of Marine Science and Engineering, 2022
A model test was carried out to reveal the vortex-induced vibration characteristics of a deep-sea riser under bidirectional shear flow. Bandpass filtering and modal analysis were used to process the test strain data, and the amplitude and frequency ...

Torsional Optical Fiber Stress Analysis and Vortex-Induced Vibration Study of Three-Core Submarine Cable

Journal of Marine Science and Engineering, 2023
Due to current scouring, submarine cables are prone to be exposed, suspended, and even vortex-induced vibration, which is not conducive to the safe operation of the power grid.

Numerical Analysis on Spanwise Correlation of Vortex-Induced Force of Split Double-Box Beam

Applied Sciences, 2022
The vortex-induced force of bridges is not synchronized along the span direction. The spatial correlation of vortex-induced force becomes obvious when the span of the bridge structure gradually increases, and the mass gradually decreases.

Vortex-Induced Vibration Suppression of Bridges by Inerter-Based Dynamic Vibration Absorbers

Shock and Vibration, 2021
The vortex-induced vibration may cause fatigue of a bridge structure, affecting the safety of vehicles and the comfort of pedestrians. Inerter is a two-terminal device, which has been applied in many areas.

Chaotic vortex induced vibrations [PDF]

Physics of Fluids, 2014
This study investigates the nature of the dynamic response of an elastically mounted cylinder immersed in a free stream. A novel method is utilized, where the motion of the body during a free vibration experiment is accurately recorded, and then a second experiment is conducted where the cylinder is externally forced to follow this recorded trajectory.
