轴压下圆柱形薄壁构件的稳定性研究

Research on the Stability of Thin-walled Cylinder Structures under the Axial-press

本文分析了轴压下圆柱形薄壁构件的稳定性,并针对工程应用需要,综合数值模拟技术得到了不同模型的屈曲载荷值,分析出圆柱形薄壁构件的屈曲载荷随圆柱壳长度、截面半径及壳厚变化的特点,修正了原有理论公式。

The paper studies the stability of thin-walled cylinder structures under axial-press. Directing toward the application demands of engineering and by classical formula, educes a new formula which changes with the cylindrical length, the sectional radius and the shell thickness, receives the buckling load of different models by numerical modeling, sums up the characteristics, modifies the original theoretical formula.
