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.

Key words
