带T型翼三体船纵向运动的预报研究

Research on motion simulation of a T-foil fitted trimaran

根据T型翼的水动力特性,分析了T型翼对船-翼系统附加质量、阻尼系数和恢复力(矩)的贡献,建立起带T型翼三体船的运动微分方程.并以某三体船为例,计算了该船及其适配T型翼在规则波与不规则波中的运动响应,结果表明:T型水翼在低速运动下没有减摇效果,在高速运动下最高可使纵摇响应幅值降低50.33%,使桥楼处加速度单幅有义值降低44.52%.

The contribution was discussed that the T-Foil does on the added mass, damp coe and restoring moment, and a T-Foil fitted based on the hydrodynamic characteristics of trimaran motion differential equation was the T-Foil. And the motion response of a estab ffi lis trimaran hed, wasalso calculated, which fitted T-Foil in different sea states. The result shows that there are no anti- rolling effect under low speed, a maximum 50.33% pitching response amplitude value reduced under high speed, and a 44.52% acceleration single significant value reduced in the forebridge.
