| 摘 要： | 船舶在真实海况中的航行性能越来越受到重视。此文在规则波中航行船舶运动的时域预报方法的基础上,发展了长峰和短峰不规则波的数值模拟技术,建立了航行船舶在长峰和短峰不规则波中运动的三维时域数值模拟方法,并应用该方法对一条10万吨油轮进行了数值模拟研究,计算了该油轮在长峰不规则波中的运动响应。试验和计算结果表明此文方法有一定的精度。最后还对该油轮进行了短峰不规则波中运动的数值模拟。长峰和短峰不规则波中的计算结果比较表明短峰不规则波对该油轮运动可产生较大影响。

| Abstract: | The predictions of ship motions in real sea become more and more important at present.In this paper,based on the time domain method for predicting ship motions in regular waves,the numerical models for long-crested and short-crested irregular wave are established.The motions of a 100000DWT tanker in long-crested and short-crested irregular waves were computed by the present method,the numerical and model tests results are compared and analyzed,the results show that the present method can well predicting the... |
