EXPERIMENTAL ANALYSIS OF RESIDUAL STRESSES AT PRODUCTS FOR THE RAILWAY TRAFFIC

Pavel Macura, Rostislav Kubala

Abstract

The contribution is devoted to the problems of residual stress measurement and reduction at the products for the railway traffic. The measurements were performed by means of cutting, ultrasonic and hole-drilling strain gage methods. Two variants of hole-drilling method were used – method with the full and incrementally drilled depth of hole. The different methods of measurement show often the different results, therefore the standards of the measurement methods for the products were worked out. At the railway traffic the standards of the measurement methods and of the allowed values of residual stresses were elaborated for railway rails, axles and wheels.
