Problems solved by technology

[0006] On the other hand, the existing coating fatigue test environment is extremely harsh (long time-consuming, loud noise, poor air, etc.), and in the test process, in order to stop the machine in time and deal with emergencies that may occur at any time, it is necessary to wait in the test around the machine, which will undoubtedly cause great physical and mental harm to scientific research workers

Abstract

The invention relates to the field of a remanufacturing coating fatigue monitoring technology and discloses a remanufacturing coating fatigue detection device. An acoustic emission sensor is arranged on a main shaft of a coating rolling contact fatigue detection device. Different characteristic parameters will appear during the initiation and propagation process of cracks inside the coating. The acoustic emission sensor can monitor the initiation and propagation process of cracks inside the coating. A characteristic parameter of the coating during unstable propagation of collective cracks is obtained, and the characteristic parameter is compared with a preset threshold value. If the characteristic parameter is greater than the preset threshold value, it is judged that the coating at the coating rolling contact fatigue detection device fails, and an alarm signal is sent out. Thus, failure of the coating is warned in advance, and life prediction accuracy of the coating is greatly enhanced. The invention also discloses a remanufacturing coating fatigue detection method.

Description

technical field [0001] The invention relates to the technical field of remanufacturing coating fatigue monitoring, in particular to a remanufacturing coating fatigue detecting device and method. Background technique [0002] Before remanufacturing waste products, it is necessary to select a suitable remanufactured coating and optimize the preparation parameters of the coating. In order to preliminarily assess the service life of the coating, it is necessary to use standard parts for rolling contact fatigue tests to predict the coating life span. The rolling contact fatigue test of the remanufactured coating is an important means to obtain the service life of the coating and evaluate the safety of service. The testing machine usually adopts the rolling contact fatigue detection device of the coating. [0003] In the prior art, the monitoring method for the failure of the remanufactured coating mainly relies on vibration sensors. The vibration sensor is pasted on the main sh...
