| 摘要: |
| 波浪滑翔器是一款新型海洋探测平台, 能够搭载重型载荷安全进行海洋探测任务是其当前急需解决的问题。本文聚焦波浪滑翔器重型悬载搭载方案, 开展了船体主尺寸及侧体布局设计, 利用流体仿真方法进行船体纵摇、垂荡和横摇运动响应分析, 并通过海上实验对设计与仿真进行理论验证。结果表明, 在波高 1.25 m、波浪周期 5.6 s 不规则波条件下, 侧体横向跨距为 0.63 m、纵向跨距为–0.525 m时, 统计概率在(μ–2σ~μ+2σ)区间的船体横摇角度在 15°以内。增设并优化侧体布局可有效改善船体横摇运动性能, 该设计虽增大了船体纵摇, 但解决了波浪滑翔器重型悬载发生倾覆的问题。 |

| Abstract: |
| This study focuses on the design of a heavy suspended carriage scheme for wave gliders, particularly on optimizing the main dimensions and side layout out of the float. Through detailed analyses of the float pitching, heaving, and rolling motion responses, we sought to enhance the stability of a wave glider. The accuracy of our simulations was validated through sea experiments. Results showed a 95.45% statistical probability that the float’s rolling angle remains within 15° under irregular wave conditions with a height (H) of 1.25 m and a period (T) of 5.6 s when the transverse and longitudinal distances of the side float are 0.63 and -0.525 m, respectively. The addition and optimization of the side layout can effectively improve the float’s rolling motion performance. Furthermore, this design solves the problem of capsizing of wave gliders carrying heavy suspended loads, although it increases the pitching motion of the float. |
