中文摘要: |
对自行设计开发的大型穿浪双体船WPC96(1 800 t级排水量)的阻力性能进行了理论预报与实验分析研究.将Michell积分推广为一般双体船兴波阻力计算公式,利用Michell积分的复积分形式进行数值编程计算,对该穿浪双体船船型在一定速度范围内的阻力性能有较高理论预报精度.在此基础上,通过改变片体间距,在理论计算和实验观测基础上研究了穿浪双体船两个片体间的兴波干扰.计算所得到的结果与实验数据基本吻合,证明该方法可以应用于穿浪双体船的阻力性能预报. |
英文摘要: |
The resistant performance of large-scale wave piercing catamaran WPC96 (1 800 t) is researched by theoretical prediction and experimental analysis. In the theoretical method, Michell integration is developed to the calculation for the wave-making resistance of usual catamarans. By the complex integration of Michell the WPC96 is numerically calculated, and the results have a high precision in a certain range of ship speed. Furthermore, by changing the distance of hulls, wave-making interaction of two hulls is studied in theoretical calculation and experimental observation. The calculated results agree well with the experimental data, which shows that this method can be applied to the resistance prediction of WPC. |
