摘要
为了提升无人艇载多波束测深系统(以下简称多波束系统)在复杂环境下的作业安全和精度,通过对多波束系统与无人艇艇型一体化安装结构的分析,采用基于有限元协同仿真技术开展动力及平台结构性能优化设计研究,设计出了在一定航行速度下能保证较优效率和航行安全的无人艇载多波束系统安装结构,并在珠江口海域进行了试验.结果表明:与传统的无人艇平台与多波束系统分离式设计的方法相比,设计的无人艇载多波束系统横摇角度小,抖动现象减弱,作业性能得到提升.运用该系统不仅可以获取水下高精度的三维地形数据,也可以为水下障碍物排查、目标物搜寻和水下构筑物巡检巡查等提供技术支撑.
Abstract
In order to enhance the accuracy and operational safety of the unmanned surface vehicle(USV)-based multibeam bathymetric system(hereinafter referred to as multibeam system)in complex environments,an integrated analysis approach combining multibeam system and hull form was employed.Leveraging advanced finite element collaborative simulation techniques,this study focused on the optimization of dynamic and platform structural performance.The research resulted in a USV-based multibeam system design that ensures superior efficiency and navigation safety at a certain cruising speed.The system was carried out experimental verification in the Pearl River Estuary.The results indicate that:Compared to conventional USV-based multibeam system in which the platform and measurement sensors are developed individually,the design of USV-based multibeam system with integrated structural optimization offers small roll angle and attenuated transducer jitter,which is also advantageous to improvement of measurement performance.The utilization of this system not only enables the acquisition of high-precision underwater three-dimensional terrain data,but also provides technical support for underwater obstacle detection,target search,and inspection of underwater structures.
