潜艇舱段结构静动力性能有限元分析

Finite Element Analysis for Static & Dynamic Performance of Submarine's Compartment Structure

采用有限元法分析和比较了两种不同非耐压船体结构形式组成的潜艇舱段结构的强度、振动和声辐射性能 .结果表明非耐压船体采用混合骨架式结构与传统的横骨架式结构相比 ,前者低频辐射噪声较后者低 5d B左右 ,抗冲击和抗碰撞性能也比后者好 。

In this paper, two different types of structures of submarine's compartments are compared in their performance of strength, vibration & sonic radiation. It can be concluded that the nonpresure hull of combination system of framing is lower 5 dB than that of traditional transverse system of framing in sonic level and the former is better than the latter in anti collision and anti impact performance, so it is a commendable style of structure.
