摘要

According to the quayside container crane (QCC), when the trolley passes by the tracks, the vibration which has features including heavy-load, high-speed and huge-impact happens. The Time-Frequency Energy Spectrum Technique based on Hilbert-Huang Transform (HHT) is put forward in this paper which is used to analyze this vibration. The application to the large-scale cranes belonged to a Shanghai container company shows that this technique can effectively monitor and evaluate the conditions of the QCC tracks and it is a new method for the monitoring and maintenance.
