Abstract
- With the rapid development of agricultural economy and the continuous improvement of modern agricultural mechanization level, agricultural machinery gradually tends to be precise and complicated, which puts forward higher requirements on the timeliness and accuracy of fault diagnosis technology of agricultural machinery. Mechanical fault diagnosis is a key technology in the field of agricultural machinery. In this paper, based on the existing theoretical knowledge, and combined with domestic and foreign literature, the fault diagnosis technology of agricultural machinery was comprehensively expounded. The research status of the four major mechanical fault diagnosis technologies of vibration monitoring, oil sample analysis, noise monitoring and infrared temperature measurement, and the time-frequency domain signal analysis methods of mechanical fault diagnosis technology were introduced in detail. Finally, the development trend of agricultural machinery fault diagnosis technologies was pointed out from different aspects, including the introduction of general machinery diagnosis technology, the continuous improvement of the application of intelligent diagnosis technology in the diagnosis of agricultural machinery faults, and the coordinated development of multiple diagnostic technologies. This paper can provide a reference for the further development of fault diagnosis technology of agricultural machinery. [ABSTRACT FROM AUTHOR]
