摘　　要：具备小长宽比、半滑行态特征的游艇线型设计与常规快艇不同,要兼顾快速性、载重吨位以及布置等多方面需求,同时半滑行艇阻力的影响机理尚不明确,所以这类船型的阻力优化仍较为困难。以约束排水量、局部尺度及其他布置相关参数的游艇全航速段减阻及改善兴波高度为目标,通过综合调研“Lackenby”变换获得初始艇型后,提炼多项局部特征参数,探究各特征参数不同取值的组合对于阻力的影响情况,利用高速船重叠网格技术进行数值模拟计算,对比前后方案的阻力及兴波情况等结果进而确定后一步优化方向,通过上述方式送代得到优化船型方案,设计模型试验,验证数值模拟精度及优化效果。经试验验证得到,目标航速优化艇型较初始艇型阻力减少18.36%,且全航速段兴波情况改善明显。The form line design of yachts with small length-width ratio and semi-glided characteristics is different from that of conventional speedboats.It is necessary to take into account the needs of speed,load tonnage and layout.At the same time,the impact mechanism of the resistance of semi-sliding boats is not clear,so it is still difficult to optimize the resistance of this type of ship.It is aimed to reduce the resistance and improve the height of the full speed section of the yacht that restrains the displacement,local scale and other relevant parameters.After obtaining the initial boat type through comprehensive research and‘Lackenby’transformation,it refines a number of local characteristic parameters and explores the impact of the combination of different values of each characteristic parameter on resistance.In addition,the high-speed ship overlap grid technology is used for numerical simulation calculation,and the resistance and boom situation of the front and rear schemes are compared to determine the direction of optimization in the next step.The optimized form type of yacht is obtained by the iteration of above method,the model test is designed to verify the numerical simulation accuracy and optimization effect.Verified through the tests,the resistance of the optimized yacht form in the target speed is 18.36% less than that of initial one,and the wave-making situation in the whole speed range has improved significantly.
