摘　　要：为研究多波束设备在无人艇上的适装性,开展测绘无人艇导流罩优化及艇型性能评估。采用计算流体力学方法,进行导流罩形状优化,并基于优化后的导流罩对艇型进行阻力及流线分析。仿真结果表明,优化后的导流罩阻力显著减小,所采用的艇型具有低阻力以及强防气泡特性;试验结果和实际作业成果进一步验证导流罩与船体线型的一体化防气泡性能仿真结果的正确性。所采用的形状优化和流线分析方法可推广至其他无人艇的阻力和防气泡性能研究。In order to study the suitability of multi-beam-system integrated on the unmanned surface vehicle(USV),the optimization of the fairing of USV and the performance evaluation of the boat shape were carried out.Computational fluid dynamics(CFD)method was used to optimize the shape of the fairing,and the resistance and streamline of the hull based on the optimized fairing were analyzed.The simulation results showed that the resistance of the optimized fairing was reduced significantly,and the adopted boat type had the characteristics of low resistance and strong anti-bubble.Experiment results and operational results showed simulation results of the characteristics of anti-bubble were correct.The adopted shape optimization and streamline analysis method can be extended to the performance research of other USV.
