摘要:
目前国内尚没有吸收塔结构设计规范,通过分析国内薄壁塔类结构相关规范,得出薄壁塔类结构的动力特性计算方法基本归结为仅考虑结构本身与仅考虑固液藕联作用两大类;根据有限元理论,对带有高塔的烟气脱硫吸收塔结构进行有限元建模,并进行了动力特性分析,对其刚度分布情况有了深入的了解;通过将有限元分析结果与按国内各薄壁塔类结构规范中的公式计算结果进行比较,得出吸收塔结构基本自振周期可按照<钢制塔式容器>中的公式进行计算,误差为4.5%.
Abstract:
At present, there is no absorption tower structure design code in China, and by analyzing the relevant specifications of domestic thin-walled tower structure, it is concluded that the dynamic characteristics calculation method of thin-walled tower structure is basically reduced to two categories: only considering the structure itself and only considering the solid-liquid coupling effect. According to the finite element theory, the structure of flue gas desulfurization absorption tower with high tower is modeled by finite element and dynamic characteristics are analyzed, and the stiffness distribution is deeply understood. By comparing the results of finite element analysis with the calculation results according to the formulas in the structural specifications of various thin-walled towers in China, it is concluded that the basic self-vibration period of the absorption tower structure can be calculated according to the formula in the > of < steel tower vessels, with an error of 4.5%.
