针对无人船在恶劣海况下船体稳定性差、推进动力不足等缺点，通过SolidWorks软件设计了一款具有波浪适应能力的无人船。利用Ansys AQWA与Maxsurf软件对船体稳性进行多维度仿真分析，最后基于STAR-CCM+软件，采用标准k-ε与VOF模型对波浪环境下的船体阻力进行数值模拟，并将仿真结果与传统经验公式计算的总阻力进行对比分析。计算表明，该无人船初稳性高为5.2 m，在静水条件与三级海浪下的大倾角稳性差异较小，且仿真阻力与计算阻力变化趋势相同。研究证实船体系统设计合理，在预定工况下，无人船的稳性与推进性能满足性能要求。
Addressing the shortcomings of unmanned surface vehicles (USVs) such as poor hull stability and inadequate propulsion under severe sea conditions, a USV with wave adaptability was designed using SolidWorks software. Multi-dimensional simulation analyses of hull stability were conducted using Ansys AQWA and Maxsurf software. Finally, based on the STAR-CCM+ software, the standard k-ε and Volume of Fluid (VOF) models were employed to numerically simulate the hull resistance in wavy environments. The simulation results were compared with the total resistance calculated using traditional empirical formulas. The calculations showed that the initial stability height of the USV was 5.2 m, with minor differences in large-angle stability between calm water conditions and sea states of up to level 3. Additionally, the simulation resistance exhibited a similar trend to the calculated resistance. The research confirmed that the hull system design was reasonable, and under the intended operating conditions, the stability and propulsion performance of the USV met the performance requirements.
