Abstract As the difficulty of knowledge acquisition of the Quayside Contain Crane (“QCC”) motor, because of the vibration characteristic, including high-speed, heavy-load and huge-impact, the analysis model of motor vibration and a quantitative analysis method of the wavelet packet based on EMD is proposed. This method can not only extract effective information from high-frequency backgrounds, but also quantize the vibration data. According to the motor vibration of a QCC (#8115) belonged to a Shanghai container-quay company, the evaluation criteria of motor healthy condition is established after analyzed and this is the effective and credible basis to evaluate the healthy conditions of QCC’s motors.
