| 摘 要： | 利用源汇分布法计算双体(或多体)剖面的水动力系数,在此基础上,对二维切片理论在双体船的垂向运动和波浪载荷预报上的应用进行了拓展,考虑了流体粘性的作用,比较了不同航速、不同片体间距和片体间水动力相互干扰等因素对运动和载荷预报的影响.算例结果表明,该方法能较好地预报双体船在规则波中的运动响应和波浪载荷.

| Abstract: | Source-sink distribution method is used to calculate the hydrodynamics coefficients of four kinds of multi-hull sections.A two-dimensional linear potential theory taking into account viscous effects is presented for the prediction of vertical motions and wave-induced loads of twin-hull vessels traveling in regular waves.Comparisons between theoretical and experimental results are shown for the responses of a Wigley catamaran.Some factors such as forward speed,distance and interaction between two hulls are also included.The comparison results show that the method of this paper can well predict the motions and wave-induced loads of catamaran in regular waves. |
