本文采用液压阻尼系统（ＨＤＳ）控制立式圆柱钢制储罐的地震反应，建立了安装ＨＤＳ储罐的力学分析模型，并进行了数值计算，从频域对安装ＨＤＳ后储罐的地震响应进行了分析，研究了ＨＤＳ的减震效果和ＨＤＳ和ＨＤＳ参数对储罐地震反应的影响。
In this paper, a hydraulic damping system (HDS) is used to control the seismic response of a vertical cylindrical steel storage tank. The mechanical analysis model of the HDS tank is established and numerical calculation is carried out. From the frequency domain, the seismic response of the storage tank after HDS installation Analyzed and studied the damping effect of HDS and HDS and HDS parameters on the tank seismic response.
