摘要： 为了更好地预报拖曳线列阵隔振模块的隔振性能，利用有限元软件ANSYS建立拖曳线列阵隔振模块的二维参数化流固耦合模型，并考虑负载(声振模块)对隔振模块的影响，将伪并行改进遗传算法与ANSYS参数化设计语言APDL相结合，实现对隔振模块主要性能参数的优化计算，得出激励频率为20 Hz和40 Hz时，隔振模块最优内部充油密度、护套弹性模量、隔振组件弹性模量和隔振量的数值。

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.
