Abstract：In order to study the effects of vibrations generated by large infrastructural equipments on surrounding buildings and environment,a vibration measurement system was designed using the magnetic levitation technology(MLT).The vibration system dynamic equation was established.It was proved that the magnetic levitation technology can be used to realize the absolute vibration measurement.The natural vibration and forced vibration of the vibration measurement system using MLT were analyzed using simulations and the power spectralanalysis.When the large infrastructure equipments work,the vibrations of surrounding buildings were measured with the system designed.The results showed that the main vibration frequency components measured are the lower frequency components of about 5 Hz; the proposed method is easy to realize the absolute low-frequency vibration measurements and has a higher sensitivity.
