摘　　要：探索单双壳体冲击环境差异对我国单双过渡型潜艇结构设计具有重要意义。采用均摊板厚的方法将某双壳体潜艇简化至对应的单壳体潜艇,利用有限元软件ABAQUS对潜艇在水下爆炸载荷作用下潜艇的冲击环境进行数值实验仿真,对加速度数据处理得到冲击谱表示的潜艇冲击环境,并将典型部位的冲击响应和沿艇长方向的响应结果分布进行对比研究。结果表明:双壳体的加速度响应值与冲击谱值同单壳体相比有相当程度的减小,双壳体潜艇的响应较单壳体潜艇的响应更具整体性。The research on the differences of impulse environment between the single-hull and the double-hull submarine has significant meaning to the structural design of the single-hull submarine. A model of a single-hull submarine is derived from a double-hull submarine by sharing the shell equally. The software ABAQUS is used to simulate the impulse environment of the submarine underwater explosion. The time history data of acceleration are transformed into an impact spectrum to get average spectral velocities. The impact responses of typical parts and along the length of submarine are compared between the single-hull and the double-hull submarine. The results indicate that the acceleration response values and the impact spectral value of the double-hull submarine are lower than that of the single-hull submarine and the responses of the double-hull submarine are more integrity.
