Vibration Carpet Value in Classification and Evaluation of the Motor Condition
According to the quayside container crane, the pitch angle of the front crossbeam only can be used to classify the states of the whole crane into operating and non-operating. The Vibration Carpet Value (VCV）is presented in this paper. By means of VCV, the motor states including working and non-working can be correctly classified. Based on the classified result, by the methodology of Wavelet Packet Quantization Analysis Technique based on EMD, the real-time monitoring and evaluation of the motor condition are more correct and effective.
