“企业”号航空母舰耐波性数值计算研究

Numerical Study on the Seakeeping Performance of USS Enterprise(CVN 65)

法国船级社研发的水动力商业软件HydroSTAR适用于多种浮式结构物在波浪上运动的预报。文章以美国"企业"号航母为例,讨论了HydroSTAR对航空母舰耐波性计算是否依然适用,并将HydroSTAR的计算结果与切片法的计算结果进行了对比。同时,将计算出的船体运动响应幅值的有义值跟与已知的统计资料进行了对比。通过对比分析发现,利用HydroSTAR计算得到的航母运动响应较为合理地反映了航母的实际耐波性能,可以为航母的耐波性计算预报提供有价值的参考。

The HydroSTAR is a version of commercial hydrodynamic software which was developed by Bureau Veritas and seen as a tool suitable for the motion predictions of a wide range of floating structures in the waves.This paper aims to discuss the adaptability of the software to the seakeeping performance prediction of USS Enterprise（CVN 65）.The calculation results derived from HydroSTAR were compared to that of the strip method.The author also calculated the significant value of hull motion utilizing P-M spectrum and compared the relevant value with recognized statistic value.Through analysis,it verified that the motion response of the carrier could well reflect the actual seakeeping performance,which is capable of evaluating seakeeping performance of aircraft carrier.
