某公务艇曲面建模及船型优化
摘 要
公务艇是一种运载公务人员,用于巡逻、执法、抗灾救援等任务的水上交通工具。与传统的船舶相比,公务艇需要具备更好的操控性、舒适性和速度性能通过改变船体的外形、船体线型和船体参数等,以降低阻力、提高速度和减少燃油消耗为目标进行优化。这包括减小船体的阻力系数、改善流场分布、优化船体的几何形状等,以提高船舶的航行性能。通过确定船型参数,船型参数包括船长、型宽、型深、吃水、方形系数、棱形系数等利用船舶原理相关知识对船舶阻力进行计算。使用MAXSURF软件选取参数不同的曲面形状进行对比分析,输出相关的阻力曲线,最后总结出不同船型变化与阻力的关系。通过对不同规格船型对比分析得出阻力小,性能良好的船型及数据。

Abstract
In order to effectively crack down on illegal and criminal activities on the water and deal with water emergencies in a timely manner, it is necessary to continuously strengthen the construction of such law enforcement teams. The official boat is a water transport vehicle that carries civil servants for patrol, law enforcement, disaster relief and other tasks. Compared to traditional ships, service boats need to have better handling, c
