本文研究水下非接触爆炸冲击载荷下高压气瓶及其管道系统冲击响应动力学建模、计算方法及减振系统优化设计方法。首先通过缩聚梁建模方法建立了某高压气瓶及其管道系统动力学计算模型，使用动态设计分析方法分析该系统承受冲击载荷时的动响应特性。为实现高压气瓶及其管道系统优化设计，基于ISIGHT软件搭建优化平台，通过二次序列规划等优化算法，对高压气瓶及其管道系统多个隔振器刚度进行组合优化设计，提高了高压气瓶及其管道减震系统的缓冲抗冲隔振能力。
In this paper, the dynamic response modeling, calculation method and vibration reduction system optimization design method of high pressure gas cylinder and pipeline system underwater explosion impact load are studied. Firstly, the dynamic of a high pressure gas cylinder and its pipeline system are established by the modeling method of condensation beam, and the DDAM dynamic response analysis method is used to analyze the dynamic response characteristics of the damping system under impact load. In order to realize the optimal design of high pressure gas cylinder and pipeline system, this paper builds an optimization platform based on ISIGHT software and quadratic sequence planning algorithm is adopted. To improve the buffer damping capacity of the damping system, The combination of the stiffness of the high pressure gas cylinder and its pipeline system is optimized.
