摘要
设计制作了基础隔震软碰撞限位实验模型与3种类型的钢螺旋弹簧限位器,给出了实测的限位器力学特性参数。进行9种工况的振动台模型实验,分析实验数据得出了软碰撞限位器参数对结构反应的影响规律,优选出了适用于本隔震实验模型的软碰撞限位工况。
The experimental model of limiting displacement of base isolation soft-collision and three kinds of steel spiral spring buffers are designed and made. The testing mechanical characteristics of a buffer are given. Nine kinds of model tests on a shaking table have been performed. The experiment data are analyzed, and the influence of soft-collision buffer＇s parameters on structural response is clarified. At last the optimized soft-collision test work cases which are suitable for this isolated experimental model are obtained.
