The magnetic levitation technology is used in the field of vibration measurement. A maglev footbridge vibration monitoring system is designed. The force on vibrator is analyzed. The vibrator kinetic equation is established. The relationship between output voltage of the vibration test systems and bridge vibration amplitude is measured. The power spectrum of measured vibration signal is obtained through data processing methods by virtual instruments. The vibration waveforms includes natural vibration of a bridge

vehicular traffic

single passer-by skywalk and many passers-by skywalk are measured. The overpass bridge vibration state is obtained by waveform analysis

power spectrum analysis. Experimental results show that the lower frequency limit of the maglev footbridge vibration

measurement system can achieve 1 Hz

the frequency measurement range of 1

190 Hz.
