圆弧滑道辊轴摩擦摆隔震系统的研究
|
摘要
提出了建筑物滚动摩擦隔震理论。根据动能定理与多体动力学理论,导出了圆弧滑道摩擦隔震系统的强非线性多自由度运动方程,并根据龙格—库塔方法给出了数值求解过程。计算了一个实例工程在地震作用下的动力反应特性。分析了辊轴摩擦隔震系统的隔震性能。辊轴式摩擦摆的结构较FPS滑道式摩擦摆有了改善。它消除了FPS型摩擦摆中滑道摩擦力的冲击作用,也不必在滑道系统中设置运动转向装置。而且在竖向也可能会有较好的隔震效果。
The theory about earthquake isolating with rolling friction is proposed in this paper.The non-linear differential equation is derived according to the theorem of kinetic energy and the theory of multiple body dynamics.The numerical evaluation procedure is presented with Longe-Kuta method.The seismic property and dynamic response on an engineering example is evaluated.This kind of earthquake isolating system possesses advantage to the FPS system because it will not exert the impulsive action to the upper structure;neither will it need the steering device which is essential in FPS.An ideal seismic isolating effect might also be attained in the vertical direction.
