摘要
柜体环向肋是威金斯气柜的主要抗风构件,工程上希望在保证安全的前提下,配置较少的环向肋,因此,本文讨论了环向肋间距及其刚度对气柜稳定性的影响。利用ANSYS的几何非线性功能,通过改变环向肋的间距及其刚度,得出环向肋的间距及其刚度是影响气柜稳定性的主要因素;而且环向肋的布置形式也是影响气柜稳定性的主要因素。
The ring stiffeners is the main wind resistance components.In the project,under the guarantee of security,people hopes arranging few ring stiffeners.So The article discusses the effect of spacing and stiffness of ring stiffeners on Wiggins gasholder ＇s stability.In this paper,Adopting the geometric-nonlinear function of ANSYS,by changing the spacing and stiffness of ring stiffeners,The author deduce that the spacing and stiffness is a main factor affecting the stability of gasholder;also the form of the ring stiffeners＇arrangement is a main factor affecting the stability of gasholder.
