Research on Parameters Rolling and Rolling Reduction of Pure Car and Truck Carrier Based on CFD
In order to explore the conditions of parametric rolling of ship,a vehicle transport ro-ro ship is taken as the research object,computational fluid dynamics(CFD)software STAR-CCM+is used to establish a virtual pool and perform numerical simulation.By simulating the free attenuation of ship roll in still water,the natural roll period of ship is calculated.The influence of wave height,wavelength,speed and encounter frequency on ship parameter roll is studied by using control variable method.The anti-roll tank is designed and carried on the ship,and the effect of anti-roll tank on parametric rollis analyzed.The results show that,when the wave reaches a certain height and the frequency of wave encounter is twice than the natural frequency of ship roll,the ship parameter roll is the most intense.When the natural period of the damping tank is equal to the natural period of the ship roll,the damping tank has a good suppression effect on the parametric roll phenomenon.
