底层柔性结构具有很好的使用功能，但该类型结构的底层常常震害严重。本文将液压阻尼控制系统ＨＤＳ安装在底层柔性结构的底层，通过地震模拟振动台试验和计算机仿真，在时域内对其进行了深入的研究。研究内容包括：液压阻尼控制系统对底层柔性结构地震反应的控制效果，控制系统的初始压力、油液刚度以及液压缸内截面积与管路内截面积的比值对液压阻尼控制系统工作性能的影响规律。得到了一些有意义的结论。 The underlying flexible structure has good use of function, but the bottom of this type of structure is often heavily damaged. In this paper, the hydraulic damping control system (HDS) is installed on the bottom of the bottom flexible structure. Through seismic simulation shaking table test and computer simulation, HDS is studied deeply in the time domain. The research contents include the influence of the hydraulic damping control system on the seismic response of the flexible bottom structure, the initial pressure of the control system, the stiffness of the fluid and the ratio of the cross-sectional area of ​​the hydraulic cylinder to the cross-sectional area of ​​the pipeline on the performance of the hydraulic damping control system law. Got some meaningful conclusions.
