Review of Research on Mechanical Fault Detection Technology

With the rapid development of the national economy and the ever-increasing living needs of people,the mechanical system is becoming more and more complex and the functions are more and more perfect.At the same time,in view of the tightness and widespread use of machinery in various industries,the occurrence of mechanical failures and detection and diagnosis technologies have also attracted the attention and research of various countries.Rotating machinery is the most widely used in machinery.Almost every mechanical system has rotating parts.Therefore,the research on the detection and diagnosis of rotating machinery faults has also attracted much attention.Here we analyze the existing research on fault detection and diagnosis from vibration signal processing technology and image processing technology,and look forward to the development direction of fault detection and diagnosis.
