摘要

摘要: 为研究热水储能罐在温度场和地震作用下的热-力耦合效应,采用附加质量法建立了热水储能罐几何模型,并且利用有限元软件ABAQUS对其进行了温度与地震的耦合作用分析。考察了空罐和热水满载两种工况下的地震响应特征。结果表明:在空罐和满载两种工况下,热水罐最大位移在X-Y平面出现的角度和在罐壁的高度均有较为显著的差异;另外,考虑热力耦合与不考虑热力耦合时最大位移出现的位置会有所不同,且考虑热力耦合时罐壁应力略小于不考虑热力耦合时的应力。因此,当进行热水储能罐抗震设计时应考虑空罐和满载两种状态,并考虑热力耦合效应带来的影响。

Abstract: In order to study the thermal-mechanical coupling effect of hot water storage tank under the action of temperature field and earthquake, the geometric model of hot water storage tank was established by using the additional mass method, and the coupling effect between temperature and earthquake was analyzed by using finite element software ABAQUS. The seismic response characteristics of empty tank and hot water full-loaded tank were investigated. The results showed that the angle of the maximum displacement in the X-Y plane and the height of the tank wall of the hot water storage tank were significantly different between the two conditions of empty tank and full-loaded tank; in addition, the position of the maximum displacement would be different when the thermal-mechanical coupling was considered, and the stress of the tank wall when the thermal mechanical coupling was considered was slightly smaller than that when the thermal-mechanical coupling was not considered.Therefore, the influence of two states of empty tank and full-loaded tank as well as the thermal coupling effect should be considered when the seismic design of the hot water storage tank was carried out.
