Study of the Frictional Surface Damage Using Acoustic Emission Method
In this study, the change at rubbing surfaces has been investigated experimentally using an acoustic emission signal monitoring system. A steel ring is slipped on the surface of a metallic sheet to simulate frictional conditions. The mechanical disturbances caused by the movement of the ring produce stress waves propagating along the sheet surface. The out of plane displacement of the sheet su...
متن کاملGeneration of Acoustic Emission from the running-in and subsequent micropitting of a mixed-elastohydrodynamic contact
This paper presents the use of Acoustic Emission to study the running-in and subsequent micropitting of a pair of hardened steel surfaces under mixed lubrication conditions. These surfaces were loaded together under rolling/sliding conditions typical of heavily loaded gearing. Relocation profilometry was used to measure the rapid running-in process and the development of micropits. Acoustic emi...
متن کاملAcoustic emission from crumpling paper.
From magnetic systems to the crust of the earth, many physical systems that exhibit a multiplicity of metastable states emit pulses with a broad power law distribution in energy. Digital audio recordings reveal that paper being crumpled, which can be easily held in hand, is such a system. Crumpling paper both using the traditional hand method and a cylindrical geometry uncovered a power law dis...
متن کاملAcoustic emission from BiSrCaCuO superconducting samples
The aim of the paper was to show if the acoustic emission (AE) signals from BiSrCaCuO ceramic superconductors appear during normal state–superconductivity transition. These AE signals were previously observed from YBaCuOtype superconducting materials. The BiSrCaCuO samples were prepared and characterised. The resistance–temperature and current–voltage characteristics of these samples were measu...
