| 摘 要： | 环肋圆柱壳一般通过在周向布置肋骨来提高其稳定性,肋骨的侧向稳定性对环肋圆柱壳整体稳定性具有重要意义。根据肋骨的侧向失稳机理,利用肋骨侧向稳定性解析解公式,在理论分析和实例计算的基础上,分析了环肋圆柱壳肋骨的几何参数与肋骨侧向失稳临界压力的关系,研究了各参数对肋骨侧向失稳临界压力的贡献值,最后得到了几何参数对肋骨侧向稳定性的影响规律。

| Abstract: | Ring stiffened cylinders usually weld ring frames along the circumferential direction to improve the stability. In this case, the frame tripping is of great significance to the overall stability of ring stiffened cylinders. According to the mechanism and the analytical solution of frame tripping, the relationship between the geometric parameters of ring stiffened cylinders and their elastic tripping pressure are analyzed both theoretically and experimentally. The contribution of different geometric parameters of ring stiffened cylinders is studied, and the effects of geometric parameters on frame tripping is finally obtained. |
