穿浪船型对高速双体船耐波性的改进

Improving the seakeeping quality of the high speed catamaran by incorporating the wave-piercing ship type

为改进高速双体船的耐波性能，采用带穿浪尖首的深V型细长片体代替一般高速双体船圆舭或前圆后尖的混合船型片体，以及在主船体首部增加一深V型抗拍击首中体。船模水池试验结果证明，带首中体的高速双体船与原艇比较，纵摇可降低15％～25％，首部加速度降低15％～20％。带有穿浪尖首片体及首中体的高速双体部与原艇比较，纵摇降低50％～60％，横摇降低25％～30％，首部加速度降低30％～40％。

To improve the seakeeping quality of the high speed catamaran, deep V slender body with wave-piercing bow is adopted instead of the composite hull form of conventional high speed catamaran with round bilge or round fore end and sharp aft end form, together with a deep V antislomming fore middle body at the bow of the main hull. The tank testing to the scaled model proved that comparing with the original design, the catamaran with the fore middle body can reduce the pitching by 15 to 25 %, and acceleration at bow by 15 to 20%,while the tatamaran with slender body and wave-piercing bow and fore middle body can reduce the pitching by 50 to 60%,rolling by 25 to 30%,and acceleration at bow by 30 to 40%.
