AE Method Sensitivity to the Progressive Cracks in Solebars of Freight-Car Trucks

V. V. Muravjev, O. V. Muravjeva

Sensitivity criteria to progressive solebar flaws at AE inspection are proved. Estimation is given of limiting sensitivity to leap sizes of fatigue cracks; sizes of fatigue crack initial zones and mechanical strain level sufficient for emission of AE waves; initial crack influence on a fatigue crack life of a part. The approaches given may be used for estimation of the AE method limiting possibilities at prediction and prolongation of a life time of other parts working under conditions of repeated loading.
