某数据中心机房楼板振动试验

Vibration test for computer room floor of a data center building

某数据中心的机房初选地址在大楼的二楼,楼底层装有空调机组,空调机组运行的强振动和强噪声对机房内的精密仪器正常工作以及操作人员的健康不利。对机房楼板的振动试验查明,空调振动将沿机房承重柱向上传到楼板、振动频率为24.5 Hz,与振源的一阶频率相当。依据国家标准对楼板振动进行了分析评价,给出了机房选址建议。

The computer room of a data center is arranged on the second floor of a building.In the basement of this building two large air conditioning sets and large pumps are installed.Considering that the strong vibration and noise of these devices in operation will be harmful to the precision computer and personal health,the vibration test of floor is carried out to find out the vibrating acceleration and frequency.The result shows that the vibration is conducted along the bearing columns to the floor,the vibratio...
