Micro-vibration Measurement and Analysis of High-Tech Electronics Workshop in Guangzhou

High-tech electronics workshop typically has stringent requirements for micro-vibration control, so as to ensure the proper operation of the installed vibration-sensitive facilities. Based on a micro-vibration measurement on a high-tech electronics workshop in Guangzhou, China, this paper reports the test data, presents a systematic and detailed summary of issues related to vibration data processing, and analyzes the transformation of the vibration characteristics when the anti-vibration techniques enhances. The results show that, the one-third octave band spectral has great advantages in representing vibration data of high-tech buildings. With the enhancement of the anti-vibration techniques, the vibration amplitudes in all of the three directions decrease both in time-history and one-third octave band spectral and finally become roughly the same; and the dominant high-frequency component disappears, while the relative low-frequency component takes the leading role in all the three directions.
