Abstract

Numerical study has been conducted for the response performance of VIV of a flexible cylinder based on modified wake oscillator model. The structure oscillator model of a flexible cylinder and wake oscillator model are established, and then the two models are coupled. Parameters analyses of non-dimensional displacement, phase angle, frequency ratio and displacement fluctuation characteristics are executed by changing non-dimensional tension, aspect ratio and mass ratio. The analysis results indicate that the VIV response of a flexible cylinder has an obvious travelling wave behavior. The propagation speed increases as non-dimensional tension increases and aspect ratio decreases, respectively. The phase angle has a sudden transition with increased non-dimensional tension and aspect ratio. The sudden transition appears at the point when the vibrating frequency passes the natural frequency.

Key words： Flexible cylinder wake oscillator model numerical study travelling wave phase angle
