摘　　要：为减小高速滑行艇驼峰航速阻力,本文开展了穿浪滑行艇驼峰阻力优化设计及水动力特性研究。研究采用船型参数化设计方法、船体阻力计算流体力学预报、拉丁超立方方法、Kriging近似模型和粒子群算法等技术。基于优化软件HEEDS,以驼峰阻力最小为优化目标建立了单体滑行艇的穿浪艏型线优化模型。并比较分析了优化后的艇型与母型艇在1.3<Fr▽<5.2范围内的水动力性能。结果表明:相对于母型艇,优化艇驼峰处阻力减小8.62%,全航速下阻力也都有所减小,驼峰航速附近减阻效果较明显。To reduce the resistance at hump speed for a high-speed planing hull,the optimization design and hydrodynamic characteristics of hump resistance in wave-piercing planing hulls were researched.The study utilized techniques such as the ship parametric design method,CFD resistance prediction,Latin hypercube method,Kriging approximate model,and particle swarm optimization algorithm.The optimization software HEEDS was employed to develop an optimization model for the wave-piercing planing hull,with the aim of minimizing hump resistance.The hydrodynamic performance of the optimized planing hull was compared with that of the parent planing hull within the range of 1.3<Fr▽<5.2.The results showed that compared with the parent planing hull,the drag of the optimized planing hull at hump speed was reduced by 8.62%.Additionally,drag was reduced across the entire speed range,with the most significant reduction observed near the hump speed.
