| 摘 要： | 通过对钛合金材料的力学性能试验数据的研究拟合出钛合金材料曲线,同时对泰勒水池公式的计算结果和有限元计算结果进行比较,将泰勒水池公式的有关思想应用于有限元分析结果的处理,对有限元分析的结果进行改进,较好地评估大深度载人潜水器耐压壳体的极限承载力。据此提出在大深度载人潜水器的耐压壳体初步设计阶段可以用该方法对结构的承载力进行预测。

| Abstract: | The material curve of the titanic alloy is fitted through the investigation on the experimental data about the mechanical properties of the alloy. By comparing the results from Taylor formula with that from the FEA (finite element analysis) and combining both results, the results obtained from the FEA are improved. The ultimate loading capacity of the pressure spherical hull can be estimated in the initial design stage of the spherical hull of the manned deep-ocean submersibles. |
