摘要:: 针对核电设备设计研制了三维隔震支座,以核电设备常用的电机为例,对其三维隔震性能开展了振动台试验研究,获得了电机设备典型部位的隔震动力响应,通过对比振动台台面数据与设备测点位置的数据来验证隔震支座的隔震效果。结果表明:随着输入地震动峰值增大,隔震支座的隔震效率差别微小,隔震效果比较稳定,说明隔震支座对电机设备起到了良好的隔震作用。

Abstract:: A three-dimensional seismic isolation bearing is designed for the nuclear power equipment.Taking the commonly used motor of nuclear power equipment as an example,we carried out a shaking table test to investigate the performance of three-dimensional seismic isolation of the motor and to obtain the seismic dynamic response of typical parts of the equipment.By comparing the data of the shaking table with the data of the measuring points on the equipment,we confirmed the effect of the seismic isolation bearing.The results show that with the increase of the peak value of the input ground motion,the difference in the isolation efficiency of the isolation bearing is small,and the isolation effect is relatively stable,indicating that the isolation bearing plays a good role in isolating the motor equipment.
