船舶附体通常根据用途设置于船体表面的特定区域，其参数特征选取会对自身的工作环境和船舶性能产生影响。本文以一型科学考察船的船底附体为研究对象，该附体主要用于安装声学研究设备，并被布置于船底特定的位置。该附体相对体积较大，且对水下工作流场环境有一定的要求。本文首先附体的流场环境需求进行分析，设定了优化原则和关键几何参数；然后建立了2个具有不同几何参数附体的船体三维模型，比例为实尺，在均匀流场中直航，来流速度为6.69 m/s，利用数值仿真的方法进行对比，筛选出流场环境最优的附体方案；随后利用参数控制优化的方法求得了具体的附体关键几何的参数，经与模型水池试验对比验证，优化参数后的附体流场环境有较明显的改善。
The ship appendage always in proper location with particular functions, whose parameters would affect the ships performance and tasks. This paper study with a geographic research ship’s appendage, which mainly used for containing ocean acoustical research devices and relatively large in volume. This paper analyzed the flow environment requirement fist, figured out the key parameter and setting the principal of optimization. Then, two ship with appendage designs with real scale 3-D geometries were built for simulation under steady states with the flow intake speed is 6.69 m/s. After tank test for comparing with these two designs, an optional design has been chosen for further optimization with parameter controlling. The optimized design has better flow environment after these work has been concluded.
