摘要:
根据拉格朗日方程推导出了椭圆滑道辊轴摩擦摆与碟型弹簧组成的三维复合隔震系统动力反应分析计算公式,考虑了竖向振动与水平向振动的耦合作用.分析与计算结果表明:隔震系统在水平向与竖向都具备必要的隔震特性,即隔离能力与复位能力;依靠摩擦作用与结构自身阻尼可以消耗传入结构的能量.当滑道长轴a=1.0m、短轴b=0.5m、滑动摩擦系数为0.01左右时,水平向隔震效率可达75%左右,在竖向也能有效减小受压层间位移与防止出现受拉层间位移,同时具有较好的消能效果与复位能力,这时滑道曲率对体系竖向振动的扰动很小,可不考虑水平向与竖向的耦合作用,各自单独计算
Abstract:
A theoretical analyzing approach about the compound seismic isolation system consisting of RFPS on ellipse slide and dish spring is derived. It starts from Lagrange Equation in multiply-body dynamics, including the coupling effect of the level vibration and vertical vibration. Computation results show that this system has the necessary isolation capability and reposition capability in the both direction; the slipping friction forces at the contacting surface provides the energy dissipation capability. It is shown that when the long axis a is 1.0m,the short axis b=0.5mand the rolling friction coefficient is about 0.01,the seismic isolation effectiveness could be as high as 75%,while the coupling effect in two directions is so small that it could be neglected and the dynamic responses could be calculated with respect to each of the individual direction
