【摘要】 对立式圆柱形钢制储液罐的固液耦合问题,从理论分析出发,通过合理建模,利用ANSYS有限元软件对4种锚固式储油罐进行了模态分析,提取前三阶阵型。同时,采用了一种试验测试方法,以确定非线性问题中的基本频率的确定问题,将此法应用于该领域,对更全面地了解储液罐固液耦合固有频率问题有着重要的作用。更多还原

【Abstract】 A finite element model of anchored liquid storage tanks were made by software ANSYS.Inherent frequency analyses of the four types of tanks in industry were analyzed.The first 3 ranks of inherent frequencies were made out.And a test method was applied to figure out the basic frequency,by applying lateral impulsive load on the foundation,there is a new approach of the free vibration response analysis of a structure-fluid interaction system.更多还原
