| 摘 要： | 为了考察初始缺陷、材料等因素对耐压圆柱壳结构极限承载力的影响，本文利用ANSYS有限元软件构造模型对耐压圆柱壳结构进行模拟．研究了缺陷幅值在一定范围内变化时，初始缺陷对耐压圆柱壳极限承载力的影响，并将有限元计算结果与理论计算结果进行比较，讨论了材料的改变对极限承载力的影响．初始缺陷幅值不会改变耐压圆柱壳结构的失稳模态，且对结构极限承载力的影响有限，但材料的改进对提高结构极限承载力的效果显著．

| Abstract: | In order to research effects of factors such as initial defects,materials to the limit load of pressure cylinder shell,this paper built models in ANSYS to simulate the pressure cylinder shell.The effects of initial defects to the limit load of pressure cylinder shell were discussed when the amplitudes of the defects vary in some extent.Moreover,the FEM results were compared with the theoretic results,and the effects of materials to the limit loads were discussed.The initial defects will not change the buckl... |
