摘　　要：[目的]为了获得兼顾静水和波浪阻力性能的优良船型,以某散货船为研究对象,开展船型综合优化设计。[方法]基于成熟的商用软件STAR-CCM+进行目标船静水阻力性能评估。采用ISO 15016推荐的简化方法和经验方法,以及自主编程开发的二维切片理论方法进行波浪增阻计算。对比分析不同波浪增阻方法计算结果与模型试验结果的差异。[结果]结果表明:二维切片理论方法计算精度较高,且能反映船型对波浪增阻的影响;目标船改型的静水阻力性能与原型相当,改型的波浪增阻和原型相比降低了20%以上,波浪中阻力性能得到显著提升。[结论]通过探讨不同波浪增阻计算方法的工程适用性,为船型综合优化设计提供了有效工具。[Objectives]In order to obtain a good hull form with both static water and wave resistance performance,a bulk carrier is taken as the research object to carry out the comprehensive optimization design of the hull form.[Methods]The evaluation of the static water resistance performance of the target ship is based on the mature commercial software STAR-CCM+.In addition to the simplified method and empirical method recommended by ISO 15016,the two-dimensional strip theory method programmed by the authors is also used to calculate the wave resistance.A comparative analysis of the differences between the calculated results of different wave added resistance calculation methods and the model test results is then performed.[Results]The results show that the calculated results of the two-dimensional strip theory method have high accuracy and can reflect the influence of ship hull form on wave added resistance;the static water resistance performance of the optimized lines of the target ship is equivalent to that of the prototype,and the wave added resistance performance of the optimized lines can be reduced by more than 20%compared with the prototype,which indicates that the resistance performance in waves is significantly improved.[Conclusions]The engineering applicability of different wave added resistance calculation methods is discussed in this paper,providing effective tools for the comprehensive optimization design of ship hull form.
