Assessment of equipment material damage by using the degree of attenuation the response of the electrical signal
The article describes the method for assessing the degree of damage to equipment material, maintained in the conditions of fatigue loading, by using the degree of attenuation of transition process the response of electrical signal. As a result of research, optimal settings of eddy current probe were identified and experimental dependencies allowing to monitor the condition of equipment material were obtained.
In this article it is offered to realize identification of limit state of the metal equipment which is operated in the conditions of fatigue loading according to parameters of electromagnetic signal response and middle and active voltages were used as the parameters. As test results it was received the experimental dependencies of these voltages on the level of the accumulated fatigue damages having the extremum which characterize the limit state of the material of the test object.
