Description

technical field [0001] The invention relates to a friction fault diagnosis method, in particular to a friction fault diagnosis method, system and readable storage medium of rotating equipment. Background technique [0002] Fault diagnosis refers to the technology of judging whether the equipment is running normally or not, and judging the cause and location of the failure, as well as the preset equipment failure state, according to various information generated during the operation of mechanical equipment in a certain working environment. Rotating equipment fault diagnosis, in terms of the characterization of the friction performance of rotating equipment, is only used for traditional performance indicators such as friction coefficient and wear amount, and uses a simple calculation method of average or maximum value, ignoring the dynamics of friction performance parameters during the operation of rotating equipment. Changes make the friction performance characterization not ...

[0002] Fault diagnosis refers to the technology of judging whether the equipment is running normally or not, and judging the cause and location of the failure, as well as the preset equipment failure state, according to various information generated during the operation of mechanical equipment in a certain working environment. Rotating equipment fault diagnosis, in terms of the characterization of the friction performance of rotating equipment, is only used for traditional performance indicators such as friction coefficient and wear amount, and uses a simple calculation method of average or maximum value, ignoring the dynamics of friction performance parameters during the operation of rotating equipment. Changes make the friction performance characterization not objective enough. In the process of friction state monitoring, there are few equipment friction fault information characterized by the temperature change of the friction contact surface, and in the process of rotating equipment monitoring, most of the parameters are independently monitored. , unable to achieve information fusion, poor monitoring and diagnosis performance
