摘要 针对在改善高速轻型穿浪双体船(WPC)迎浪中波长与船长接近时纵向运动幅度较大的缺点,采用了理论计算与模型试验相结合的方法,对250 t级穿浪双体船开展了水翼改善纵向运动的理论和试验研究,分析了水翼形式、尺度和安装位置等对纵向运动的影响规律。数值计算和试验结果的比较表明,计及水翼—船体水动力干扰影响的切片理论可满足WPC加水翼后波浪中纵向运动计算的需要,但在纵向运动响应峰值处数值计算结果偏高。模型试验表明,250 t级WPC加装水翼后,迎浪纵摇和垂荡有义幅值可减少20%~30%。 The pitch and heave motion range of high speed light wave-piercing catamaran(WPC) in head sea would become much higher while wave length near the ship length.Theoretical approaches together with model test were induced to provide a longitudinal motion performance improvement for a 250 t WPC using hydrofoils.The influence of the hydrofoils parameters,such as the shape,size and mounting locations,were investigated.A comparison of numerical calculation results and test data suggests that the strip method,with hydrodynamic interactions between hydrofoil and the hull taken into account,is applicable to the longitudinal motion prediction of WPC with hydrofoils,though the calculated RAO is a little bigger which near the RAO peak value.Based on the model test data,the significant amplitude of heave and pitch of the tested model in head sea reduced 20%~30% with the hydrofoils installed.
