摘要
建立了圆柱形水下航行器壳体外形多目标优化设计的数学模型。基于灵敏度分析结论,采用插值折算的方法对数学模型进行改进,提高了计算精度和效率。水洞试验和计算结果表明,优化外形的阻力有较大降低,噪声性能有一定改善。
This paper puts forward the optimal design model of cylindrical shape of UUV. Based on the analysis of sensitivity, the model is improved and so are the computational precision and efficiency. The experiments in water tunnel and the design data indicate that the drag and noise of the optimal shape are improved.
