中文摘要:
      本文运用CFD软件STAR-CCM+建立三体船在波浪条件下的三维砰击模型,采用重叠网格技术结合船舶六自由度系统模拟船体的砰击运动,对不同波高、波长以及不同航速下的船体砰击进行数值模拟,对比分析各工况下船体结构的运动响应和砰击特征。数值模拟结果表明:航速变化对船体砰击压力有显著影响,而波高和波长的变化对砰击压力影响较小但也不可忽视。
英文摘要:
      This paper uses CFD software STAR-CCM+ to build the 3D slamming model of trimaran under sea wave condition. By using overlapping mesh method and Six Degrees of Freedom System of Boat, we run slamming numerical simulation in different wave length, wave height and speed. Then we compare and analyze the movement response and slamming characteristics of hull structure and the result shows that the speed has a great influence on slamming pressure while the wave length and wave height have less influence but also pivotal.
