| 摘 要： | 针对超空泡水下航行器壳体尾部受到空泡壁面冲击作用的特点,建立超空泡水下航行器壳体有限元模型,对航行器壳体结构进行谐响应分析,并比较普通圆柱壳体与渐缩壳体、环向加肋壳体以及双层壳体的性能.对四种壳体形式的优化计算表明,环向加肋壳体在满足位移和应力约束条件下的最小质量仅为4.152 kg,为较优的壳体形式；双层壳体优化得到的最小质量为7.228 kg,在超空泡水下航行器结构设计中具有潜在的发展优势.

| Abstract: | A finite element model of the supercavitating underwater vehicle is developed and the frequency response analyses are performed considering the interactions between the shell and the interior surface of the cavity.The performance of plain shells is compared to those of stiffened,tapered and double shells,and the structural configurations are then optimized.The computational results show that the stiffened shell configuration is more beneficial,the optimal mass of which is 4.152 kg with the constraints of the displacement and the stress,and the double shell configuration has the potential advantage,the optimal mass of which is 7.228 kg. |
