英文摘要：

Based on the CFD method, numerical wave tank is built and the numerical simulation is carried out for the added resistance, the pitch and the heave of the high speed trimaran in regular heading waves. Using FINE/Marine software, we simulate regular waves by wave generator which is based on the Stokes wave theory, and eliminate the influence of wave reflection by setting the boundary conditions. By choosing appropriate size of computational domain and refining the mesh in the range of wave height in the computational domain, we are able to improve the accuracy of numerical calculation. The pitch and heave motion of the ship model in regular heading waves is simulated by setting the six degrees of freedom. Based on the data of ship model test, calculations are made for the added resistance and motion response of pitch and heave of the trimaran model in regular heading waves, then the results are compared with the experimental data.
