摘　　要：为提高多用途船的航行性能与营运经济性,在满足布置要求基础上,通过全参数化建模及多种优化算法,针对多用途船船艉、船艏以及全船进行船型优化。采用高精度黏性求解器完成阻力计算,通过对比分析不同优化船型实尺度下的船舶航行阻力及伴流目标函数,完成多用途船的型线优化设计。优化得到的船型较初版型线其剩余阻力减小24. 51%,伴流目标函数减小8. 6%。To improve the navigation performance and operation economy of multi-purpose vessels,the three rounds of ship hull optimization were performed for stern,bow and whole line respectively by full parametric modeling and a variety of optimization algorithms.The high fidelity viscous solver was used to perform the drag calculation.By comparing and analyzing the full-scale sailing resistance and the wake object function,the optimization design of multi-purpose vessel was completed.The residual resistance of the optimized ship model was 24.51%less than that of the original version,and the wake object function decreases by 8.6%.
