Low-Frequency Vibration Testing of Huge Bucket Wheel Excavator Based on Step-Decay Signals

The low-frequency vibration of the bucket wheel excavator has an important impact on the fatigue life of the structures. For conventional vibration testing methods, it is difficult and expensive to excite the overall low-frequency vibration of the whole machine. Hence, in this paper, the excitation...
