Enhancement of the acoustic-emission method use for diagnostics of rolling stock cast parts
Source abstract
Abstract
The techniques for acoustic-emission (AE) testing of cast parts (side frames and bogie bolsters) of a freight-car truck, which improve the reliability of evaluating their engineering state at different stages of the working cycle and decrease their repeated rejection, are considered. It is proposed to determine the degree of damage and the service life of cast parts on the basis of the analysis of AE-signal sources, which have the highest integral characteristics.
