The Simulation Research of Damping Characteristics for the Underwater Vehicle Moving under or Exceeding Water

Abstract:

The vehicle may vibrate when it moves under or exceeding water. This vibration will interact with the flow filed around to form a fluid-structure interactiondynamics system. In this paper, the numerical simulation of a cylinder in the process of moving under or exceeding water with ABAQUS and FLUENT is presented. Simultaneously, the first three damping ratio of the system are obtained by damping identification. For different density, viscosity and velocity of water, model separately to get the impact of each factor. Besides, the continuous process of exceeding water has been discretized to obtaindifferent oscillating curvesat different positions with respect to the water,and then the change of the damping ratio is presented. Thus the damping characteristics of the system in the water-exit process have been obtained approximately.
