摘　　要：二维半理论在单体和多体高速排水式船的耐波性预报中具有很好的数值预报精度。文中在二维半理论稳定求解高速船水动力和运动响应的基础之上,采用数值差分方法对高速船水动压力进行了计算,针对一条SL-7集装箱船进行了水动压力的数值预报,结果同模型试验结果进行了比较,表明文中提出的方法能够较好地预报高速船舶的线性脉动水动压力。The 2.5D theory developed in recent years has satisfactory numerical accuracy by validation with model test data for the numerical prediction of seakeeping for mono-hull and multi-hull displacement ships.In this paper,the numerical differentiation algorithm is proposed to calculate the hydrodynamic pressure of high speed vessels based on the stable solution of hydrodynamics and ship motions using 2.5D theory.The numerical prediction of hydrodynamic pressure for a SL-7 containership model is performed and compared with the model test data.The numerical comparison shows that numerical algorithm given in this paper can be used for the prediction of hydrodynamic pressure of high speed vessels.
