为满足内河8 kn水流条件下航行器稳定航行性能要求，提出一种低流阻、可快速拆卸水下遥控航行器（ROV）总体结构。采用外部流线外形+内部开放框架的设计方法：外部采用Nystrom线型形成外形框架，通过样条曲面生成技术生成外形曲面，完成流体外形设计；内部框架采用横骨架式承载结构，使用标准型材组装框架，各传感器、机电设备、浮体及尾部平衡翼与框架固连。经流体阻力仿真及框架结构有限元冲击仿真分析，流体阻力较开架式总体结构减小90%以上，抗冲击性能可靠，能够满足高流速下的航行要求。本文减阻结构设计方法兼顾了减阻、模块化快速拆装和低成本易实现等优点，对其他水下航行器总体结构设计具有借鉴意义。
In order to meet the requirement of stable navigation performance of the underwater remote control vehicle (ROV) under the con-dition of 8 water-saving flow in inland river, a low resistance and rapid expansion structure of the ROV is studied. The design method of external streamlined shape + internal open frame is adopted: Nystrom linear shape frame is used to form external shape frame, Bessel spline surface generation technology is used to generate external shape surface and complete fluid shape design; the internal frame adopts transverse skeleton bearing structure, uses standard profiles to assemble frame, sensors and electromechan-ical equipment. The floating body and the tail balancing wing are fixed to the frame, and the tail balancing wing is added to im-prove the overall static stability. Through the fluid resistance simulation and finite element impact simulation analysis of frame structure, the fluid resistance is reduced by more than 90% compared with the open-shelf structure, and the anti-impact perfor-mance is reliable, which can meet the navigation requirements at high velocity. This drag reduction structure design method takes into account the advantages of drag reduction, modular rapid disassembly and assembly, low cost and easy realization, and has reference significance for the overall structure design of other underwater vehicles.
