摘要
对一条8000TEU集装箱船进行线型优化时不仅考虑了静水阻力性能,还将参数横摇指标用于判断集装箱船线型的优劣。在获得8000TEU集装箱船两个优化方案的静水阻力后,采用非线性时域面元法对两个方案的参数横摇进行了系统分析。分析结果表明,在相近静水阻力性能和同样的海况中,A1方案的最大参数横摇幅值明显小于A0方案。论文研究为集装箱船性能的优化增加一项目标,为集装箱船线型优化设计提供了新的思路。
In this paper, the lines optimization of an 8000TEU container ship is carried out to reducing calm water resistance and parametric roll. The nonlinear panel method in time domain is adopted to analyze the parametric rolling for two variants of the 8000TEU container ship. Numerical results show that the maximum roll angle of variant A1 is significantly greater than that of variant A0, while the two variants have nearly the same calm water resistance. A new concept is established for the line optimization of container vessel.
