摘要
采用CCS规范方法、DNV规范方法和CFD方法对一艘运输集装箱起重机的甲板运输船的风载荷进行计算比较分析,从分析角度、风剖面形式等方面对比CFD方法和规范方法在受风构件风载荷计算上的差异。讨论了起重机构件间遮蔽效应的影响,在某些风向遮蔽效应影响复杂的情况下,规范方法的计算结果较CFD方法结果明显偏于保守。本研究可为船舶设计人员更合理地评估风载荷提供参考,以保证船舶运营的安全。
Wind load on a deck carrier,which carries four container cranes,is calculated and analyzed with several methods such as CCS standard,DNV standard and CFD.Because of the difference in analyzing object and the wind speed profile between CCS and DNV standards,there are significant changes in the results.The wind load calculated with CFD is lower than others in the case of complicated shielding effect.With the help of CFD,the shielding effect is taken into account in different wind directions.It is hoped that the work would be helpful to ship designers in balancing design index and safety.
