【摘要】 介绍WYD-1地震仪表系统信息处理机柜的抗震试验。试验利用三维振动台,采用与设备安装楼面反应谱相容的人工时程的多频试验方式,对地震监测系统进行白噪声探查和5次运行基准地震及1次极限安全地震试验,试验验证了WYD-1地震仪表系统在地震载荷作用下能正常工作。更多还原

【Abstract】 The seismic test for the information processing cabinet of the seismic instrument system WYD-1 is introduced.For the test using a 3-D vibration table and adopting the multi-frequency test mode of the artificial history which is campatible to the response spectrum of the floor on which the equipment is installed,we detected the white noise and carried out the tests of OBE(operational base earthquake) five times and the SSE(safety shutdown earthquake) one time.These tests proved that the seismic instrument system WYD-1 can work normally under the effect of earthquake load.更多还原
