拖曳线列阵隔振模块采用遗传算法的参数优化
Parametric Optimization of Towed Line Array's Vibration Isolation Modules Base on Pseudo - parallel Improved Genetic Algorithm
摘要
Abstract
In order to predict the vibration isolation capability of towed line array vibration isolation modules, a planar fluid-structure coupling model of the array is constructed by means of ANSYS code. And the vibration isolation capability is calculated with the consideration of the influence of the load (acoustic module) on the vibration isolation modules. Pseudo-parallel improved genetic algorithm and ANSYS' s parameterized design language APDL are combined to realize the optimization of the main parameters of the vibration isolation modules. And the optimal values of internal oil density, optimal elastic moduli of hull and the components of the isolation modules for 20Hz and 40 Hz exciting frequencies are obtained. This work provides a reference for improving the performance of vibration isolation modules.关键词
