| Abstract: | To improve the efficiency of port loading & unloading and realize port automatic loading & unloading, the numerical wave tank is used to simulate the wave compensation issue during port loading & unloading of ships. A numerical model of wave compensation is built based on CFD theory during port loading & unloading of ships. The numerical wave tank with three different waveforms is built by the boundary wave generating module of Flow 3D, where wave absorbing is by the boundary condition of Sommerfeld radiation and the porous medium model. CAD is adopted to conduct numerical analysis on wave compensation during port loading & unloading of ships. Ultimately, the wave compensation during port loading & unloading of ships is transferred to the displacement compensation of cranes. The simulation result indicates that the method meets the engineering requirements and provides technical support for the realization of port automatic loading & unloading. |
