摘要
本文提出一种用于潜艇冲击响应分析的结构建模方法,将潜艇结构简化为等截面梁,计算结构振动频率,利用结构振动频率、水下爆炸冲击波能量和舱室破损数量构建潜艇结构总体模型。利用模块化设计方法设计和构建潜艇耐压壳体结构、舱壁结构、甲板结构和压铁,并参照实际情况设计各模块的组装方式。通过对结构各个模块基本参数的确定,对潜艇总体尺寸与质量、振动频率和重心位置等总体指标进行计算与控制,使得模型与实艇具有良好的一致性,为潜艇结构冲击响应分析提供手段。
In this paper,the submarine structure is simplified as a beam with constant cross-section,and the vibration frequency of the structure is calculated.The overall model of submarine structure is constructed by using the structural vibration frequency,underwater explosion shock wave energy and cabin damage number.The pressure hull structure,bulkhead structure,deck structure and pressure iron of submarine are designed and constructed by modular design method,and the assembly mode of each module is designed according to the actual situation.Through the determination of the basic parameters of each module of the structure,the overall size and mass,vibration frequency and center of gravity position of the submarine are calculated and controlled,which makes the model and the real ship have good consistency.
