摘要:
立式储罐结构在工程实际中得到广泛的应用。本文以某大型立式储罐结构为例,考虑到液体、结构、地基的相互作用与影响,同时考虑地基与结构及液体与结构的耦合问题,采用有限元方法对浮放在地基上的储罐结构进行了自振特性计算。分别计算了满罐和空罐时系统的频率以及所对应的振型图,并研究了储罐的材料参数和地基刚度对动力特性的影响。结果表明:材料参数的影响较小,地基刚度的影响较大,对盛满液体与空罐的影响不同。
Abstract:
Stand storage tank is extensively applied in practical engineering.In this paper,the dynamic responses of the stand storage tank supported directly on the flexible soil foundation are analyzed by using the finite element method,and considering the interaction among fluid,structure and foundation.Frequencies and modes of full tank and empty tank are calculated.The results show that the effects of material parameters are small,while the effects of the modulus of the foundation are apparent.
