Abstract

In this paper, the global motions and wave loads on a large bow-flare ship in oblique regular waves considering hydroelastic effects are studied both numerically and experimentally. Numerical simulations of the ship's asymmetrical motions and loads in waves are conducted using a CFD-FEM two-way coupled method. The segmented model tank test is also conducted by using a hybrid structural backbone beam to measure both the sectional vertical bending moment and torsional moment. The numerical results are verified and validated by analyzing the ship modal behaviour, roll free decay curve, motions and loads and comparing with the experiment results. The influence of wave heading angle, wave length, wave height and ship speed on the wave loads including sectional bending moment and torsion moment are comprehensively studied with the numerical and experimental results. The relationship among vertical bending moment, horizontal bending moment and torsion moment is also discussed.

非对称波浪载荷和船舶在斜向规则波浪中的水弹性响应的数值和实验研究
本文从数值和实验两方面研究了考虑到水弹性效应的倾斜规则波浪中大型艏侧帆船的全局运动和波浪载荷。采用 CFD-FEM 双向耦合方法对船舶在波浪中的不对称运动和载荷进行了数值模拟。此外,还使用混合结构骨架梁进行了分段模型油舱试验,以测量断面垂直弯矩和扭转力矩。通过分析船舶模态行为、自由滚动衰减曲线、运动和载荷,并与实验结果进行比较,对数值结果进行了验证和确认。结合数值和实验结果,全面研究了波向角、波长、波高和船速对波浪载荷(包括截面弯曲力矩和扭转力矩)的影响。还讨论了垂直弯矩、水平弯矩和扭转力矩之间的关系。
