摘　　要：研究适用于大方形系数半滑行艇的浅槽消波艇型,在常规尖舭方艉艇型的基础上进行改进设计,在艇底部设计了一个从艏部至舯部的浅槽道,以改善阻力与兴波性能。开展了该新型浅槽消波艇型与常规艇型性能的对比试验研究,分析了艇体周围流场、艏、艉兴波、航行姿态及阻力的试验结果,表明新型浅槽消波艇型具有艏艉兴波小、艇体阻力低等特点。This paper introduces a type of wave absorbing hull form with a shallow groove which is suitable for semi-planing vessel with large form coefficient to reduce resistance and wave making.Flow field around the hull,wave making at the bow and stern,navigation attitude and resistance are analyzed.Experimental results show that this new type of hull form has the feature of less wave making at the bow and the stern and lower resistance of the hull than the conventional hull form.
