基于CSSO算法的抛弃式探头结构优化设计

在海洋水文探测系统中,抛弃式探头是整个探测系统的核心,也是探测工作的执行者。为了得到准确有效的探测数据,就需要对抛弃式探头做进一步的优化设计。采用多学科设计优化方法(multi-disciplinary design optimization,MDO)中的并行子空间优化方法 (concurrent subspace optimization,CSSO)对抛弃式探头进行设计。首先对系统进行分析,得到系统分析的近似模型,其次对并行的子学科进行优化,再次更新系统分析模型,最后验证优化模型的收敛性。结合抛弃式探头的结构,选取了头部进行了优化设计,给出了圆环型、半圆型、圆锥型3种设计方法。利用CAD软件画出三维仿真模型,然后用CFD软件进行流体工作环境仿真,最终确定半圆型头部探头为最优化设计探头。

Optimized design of profile probe structure based on concurrent subspace optimization

In marine hydrological detection systems, the profile probe is the core of the entire detection system and the performer of the detection work. In order to obtain accurate and effective detection data, it is necessary to further optimize the design of the disposable probe. The profile probe is designed to use the concurrent subspace optimization(CSSO) in multi-disciplinary design optimization(MDO). Firstly, the system is analyzed, and the approximate model of the system analysis is obtained. Secondly, the parallel sub-disciplines are optimized, the system analysis model is updated again. Finally the convergence of the optimization model is verified. Combined with the structure of the profile probe, the head was optimized and three design methods of ring, semicircle and cone were given. The CAD software is used to draw the 3D simulation model, and then the CFD software is used to simulate the fluid working environment, and finally the semicircular head probe is optimized to design the probe.
