| 摘 要： | 对一定几何尺寸、水深下的潜艇耐压舱段，设计满足强度和稳定性要求的较佳结构；以环肋柱壳为例分析各结构尺寸对其强度和稳定性的影响，并对其在流场中的振动频率进行计算分析。本设计及频率计算采用C#语言自编程序软件，快捷准确有较强实用性和工程意义。最后采用软件Ansys建立环肋柱壳模型，计算其失稳压力及频率，进一步证明理论分析结果的可靠性。

| Abstract: | Design the submarine shell with the given dimensions and submergible depth in accord with the standards of strength and stability, then choose the optimal structure. Discuss the influence of stress and buckling stress between dimensions of the cylindrical shell. Analyze the characteristic of vibration of the cylindrical shell and discuss the influence between frequency and dimensions in various cases. To ease the design, use the C# computer language programming a software which is convenient, accurate and can automatically choose the lightest structure. Finally, use the FEA software-Ansys to build the computational model and calculate the stresses and frequencies, which can be compared with the analytical results. The comparisons verify the reliability of the program and the theoretical analysis. |
