关于可变船USV航行性能研究

Study on variable sailing ship USV performance

型宽值是船舶性能中的一个重要参数,在船舶的稳定性、耐波性以及快速性中起着关键作用。相对于复杂多变的环境,固定型宽的船舶难以应付,而可变船宽更能够改变型宽以适应复杂环境下的工作。文章通过一种机械式可变船宽的方法设计制作了可变船宽双体USV,并由APM控制系统记录下USV航行轨迹,进而再从船的不同型宽入手,对船舶的航行阻力及稳定性进行研究,确定船舶航行时的最佳型宽比以满足船舶安全舒适性同时减少能耗,提升续航力,为船舶在复杂环境下的工作以及节能方面提供了参考。

Type wide value is an important parameter in ship performance, in the stability of the ship, seakeeping and quickness plays a key role. Relative to the complicated and changeable environment, fixed type ship is difficult to cope with wide, instead of variable width is more wide type can change to adapt to the complex working environment. In this paper, a mechanical variable method to design the variable boat ship wide wide catamaran USV, and record the USV is controlled by the APM system trajectory, and then from different type of wide, study of ship resistance and stability of the ship, determine the best type of navigation when wide than to meet the ship safety comfort while reducing energy consumption, improve endurance, for the ship working in the complex environment and provides reference to save.
