An Analysis of UT Echoes Coming from Fatigue Cracks and Artificial Defects on Railway Axles
Non Destructive Testing applied to railway axles is performed both in production and in maintenance. During production, NDT is carried out at different stages adopting different techniques, while during maintenance (in-service inspection) only ultrasonic testing is usually carried out. The present paper is focused on some aspects of calibration related to the in-service inspection of railway ax...

15 صفحه اولFatigue system reliability analysis of riveted railway bridge connections
A system-based model for fatigue assessment of riveted railway bridge connections, comprising a number of basic components, is presented in this paper. Probabilistic fatigue load spectra are developed through Monte Carlo simulation of train passages over a finite element model of a typical, short-span bridge. Uncertainties arising from loading, resistance and modelling sources are taken into ac...

متن کاملPermeability and Direct Shear Tests Characteristics of Railway Subballast
Permeability, filtration and shearing strength were widely considered to be the key properties in evaluating the performance of railway subballast. An investigation on these key properties of railway subballast was presented in this paper. A constant head permeability test and a middle scale direct shear test of railway subballast were conducted in the research, aiming to investigate the subbal...
