本文研究了水下非接触爆炸冲击载荷下复杂细长结构冲击响应动力学建模、计算方法及减振系统优化设计方法。通过缩聚梁建模方法建立了某复杂细长结构减振系统动力学计算模型，分析了该细长结构承受冲击载荷时的动响应特性。为实现细长结构减振系统优化设计，通过APDL编程建模实现了缩聚模型中减振垫位置参数化建模，基于二次序列规划优化算法，对减振垫布置、刚度进行了优化设计，提高了细长结构减振系统的缓冲减振能力。
In this paper, the dynamic modeling and the calculation method of the dynamic response of complex slender structure under the impact load of underwater non-contact explosion are studied, and the vibration reduction system optimization is also explored. Firstly, a condensation beam model of an underwater vehicle damping system is established, then the dynamic response characteristics of the slender structure under impact load are analyzed. To achieve optimization, the parametric modeling of position of the condensation beam model vibration damping element is realized based on APDL language programming. Finally, base on the quadratic sequence optimization stiffness of the damping elements in the damping system are optimized, which greatly improves the buffering and damping performance of the damping system.
