垂直微结构剖面仪是获取海洋微结构湍流数据最有效的测量平台，其下降过程中产生的流致振动是影响剖面仪测量精度的主要因素。分析了影响剖面仪流致振动的因素，基于 ANSYS-Work-bench数值仿真平台，采用双向流固耦合算法，得到了剖面仪流致振动与其结构外形及参数之间的关系。在此基础上，以减小流致振动为目标，采用单目标优化方法分别对剖面仪主体结构外形及结构参数进行了优化，优化后的剖面仪测量精度提高了57％。研究成果为垂直微结构剖面仪及类似结构的合理设计提供了理论指导。

Vertical microstructure profiler (VMP)is a most common and effective platform to ob-tain data of microstructure turbulence in the ocean.The FIV is the main factor affecting the measure-ment precision of the VMP.Factors influencing the FIV of the VMP were analyzed herein.Based on the numerical simulation platform of ANSYS-Workbench,the FIV of the VMP with various shapes and structure parameters was calculated using algorithm of two-way fluid-structure coupling.Aimed to decrease the FIV,the main body shape and the structure parameters of the main body were opti-mized respectively.The measurement precision of the optimized profiler is improved by 5 7%.The present investigation provides scientific guidance for designing the VMP.
