大型半潜船球首设计及阻力性能对比分析
|
摘要
为了掌握10万吨级半潜船的船型自主研发技术,文章设计了2种大型半潜船的船型,采用了直立型和短球首型两种不同的球艏,通过其船模静水阻力试验的方式对两型船进行对比,推出阻力性能较优的短球鼻首型式。另外通过对两型船的阻力试验结果进行对比,检验船尾伴流场,为10万吨级半潜船的船舶球鼻首设计提供参考。
In order to master the independent research and development technology of the ship type of the 100 000 t semi-submersible ship, the paper designs two large semi-submersible ship types, using two different bows, the upright type and the bulbous bow type. By comparing the two types of ships through the ship model hydrostatic resistance test, the bulbous bow type with better resistance performance is put forward. In addition, by comparing the resistance test results of the two types of ships, the stern companion flow field is tested to provide reference for the ship's bow design of the 100 000 t semi-submersible ship.
