Limiting Performance Analysis of Underwater Shock Isolation System Based on Genetic Algorithm

在舰船上安装隔离器可以减小水下冲击的影响起到保护仪器的作用。通过构造一个冲击激励-船体-隔离装置-仪器的交互作用模型,计算出仪器的动力响应。基于这一模型,设计适宜的冲击隔离系统,满足它的性能指标。然后用遗传算法来解决传统优化方法很难解决的最优化问题。最后,通过一个算例及结果分析,获得其极限性能特性。

Protection of equipment from underwater shock is implemented by installing isolators. A simple shock-structure-isolation-equipment model is constructed. The model incorporates the effect of fluid-structure interaction, response of equipment and isolator influence. Based on this model, the optimum shock isolation is then formulated. Finally, GA is applied to an example problem and the limiting performance characteristic is obtained.
