摘要：
The dynamic behavior of deep sea risers is more complicated under vortex induced vibration(VIV)due to the current considering parametric excitations aroused by the heave of the platform. In this experiment, the riser model was dragged by a towing tank in the pool to imitate the riser's movement of VIV under uniform current and the top of the model was connected to a tensioner, which was made by a linkage with controlled frequency and stroke, to imitate the influence of the heave of the platform to the top of the riser. In this way, the experiment of the riser under VIV considering parametric excitations was made and the effects of the current speed, top tension as well as the parametric excitations to the risers were studied. The results show that the vibration stress of riser increases as the current speed increases and decreases as the top tension increases. The dominant frequency of riser is controlled by the current speed and is hardly influenced by the top tension. The VIV response of riser is larger due to the parametric excitation. The vibration stress of the riser increases as the heave amplitude or frequency of the platform increase. The parametric excitation frequency occurs and becomes a part of vibrational frequency of the riser. © 2016, Tianjin University. All right reserved.
