摘要
针对细长体船,研究了耐波性预报方法。基于二维切片理论和三维势流理论方法,计算得出传递函数,采用谱分析法对耐波性进行了短期预报。以某300 t级执法船为例,进行了计算并与船模试验结果进行了比较,得到的结论对高速海洋执法船的耐波性研究提供了重要参考,也为细长体船耐波性的评估提供了一定的参考价值。
The seakeeping analysis of a slender ship is presented in this paper. The analysis is carried out based on strip theory and 3D potential theory. Transfer functions of motions are obtained and the short term predictions of motion responses based on wave spectra and transfer functions are also presented. A case study of 300 t class coastguard ship is carried out and the results from it are compared with those from the model test. The outcomecould be a reference to the seakeeping analysis of high speed coastguard ship and other ofslender ships.
