| Abstract: |
| The U-tube type anti-rolling tank has been generally used to reduce roll motion.Due to the complex inner structure of the tank which leads to nonlinear sloshing,predicting characters and stabilization effect is difficult.In this paper,a nonlinear ship motion simulation is achieved by using numerical method,which is real-time coupled with the sloshing in the tank.The data of flow and torque is collected,and the range of stabilization effect is obtained by analyzing the power spectrum.Compared with the result of bench test,the simulation result is confirmed,which also indicates that the anti-rolling tank could provide stabilization effect under its frequency range. |
