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 rolling friction and isolation theory of buildings is put forward. According to kinetic energy theorem and multi-body dynamics theory, the strong non-linear multi-degree-of-freedom equations of motion of arc chute friction isolation system are deduced. The numerical solution process is given according to Runge-Kutta method. The dynamic response of an example project under earthquake action is calculated. The isolation performance of roller friction isolation system is analyzed. Roller-type friction pendulum structure than FPS slide friction has been improved. It eliminates the impact of FPS-type friction pendulum friction in the slide, and does not have to set the motion steering device in the chute system. And vertical may also have better isolation effect.
