| Abstract: | The piston air-compressor performs its main functions when it is reciprocating, with vibration being one of the signs of its malfunction. Based on the incentive signals caused by coupled vibrations of all moving parts of the compressor, vibration signals of each component can be modeled and features of impact response signals can be extracted. Then through comprehensive analysis of these signals in time domain and frequency domain, fault feature parameters and criteria can be acquired for the common malfunction diagnosis of the compressor. |
