以ANSYS软件为平台,理想塑性材料力学模型和Mises屈服准则为基础,建立了存在均匀层间间隙的多层容器弹塑性有限元模型,结合实验数据测定现有制造工艺下多层容器的层间间隙参考范围为0.055~0.13 mm。以同尺寸单层容器Mises初始屈服压力作为超压处理压力,模拟改善应力分布效果。

A elastic-plastic finite element model(FEM) of multi-layer vessel with uniform gaps was established,based on ideal plastic material and Mises yield criteria,using ANSYS software.The value of each gap in finite element model was 0.055~0.13 mm after matching the test data.The effect on stress distribution improvement simulated under the super pressure treatment(SPT) of the Mises initial yield pressure of monolayered cylinder with the same size was presented.
