AN INVESTIGATION TO DYNAMIC PROPERTIES OF SERIALLY ISOLATED SYSTEM BASED ON SWEEP SINE SHAKING TABLE TEST

摘要：

New-style isolation device for serially isolated system is presented by the dynamic analysis to serially isolated system. This device has small horizontal stiffness and the difference of this device with rubber-lead bearing is that this device can resist biggish vertical tensile force. Then the experiment for small-scale model of this device based on sweep sine shaking table is performed. The result shows that serially isolated system with this device can prolong natural period of serial system and effectively decrease the response of superstructure and have good isolated performance and stability.
