基于有限元分析的垂直阵阵形预报

Shape prediction of vertical line array using finite element analysis

针对上端固定、下端悬挂配重的垂直阵系统,利用有限元分析软件建立阵形预报模型,阐述建模中单元的选取和载荷的施加过程。利用该模型分别对定常流和复杂流作用下垂直阵的阵形进行预报,并讨论配重对阵形的影响,给出合理配重方案。本文提出的方法具有一定的工程应用价值。

Aiming at the surface moored acoustic vertical line array,a shape prediction model is established using the Ansys software.The modeling processes of element selection and load application are described in detail.With the established model,the array shapes of vertical line array are predicted under both steady ocean current and complex ocean current circumstances.The impacts of different weight on array shape are also discussed,and a reasonable scheme of weight configuration is obtained.The proposed method will play an important role in engineering application.
