WHEELSET RESEARCH AND DEVELOPMENT IN THE BRITISH STEEL CORPORATION
This paper reviews recent activities of the Sheffield Laboratories. Metallurgical studies have shown thermal cracking in wheels increases with yield strength and reduces with ductility. Finite element analysis shows lower stresses in the typical European double-curved plate wheel than in the American straight-plate design. While high compressive residual stresses are generated in tread surfaces by service, tread braking does not affect residuals in plates. In disc braked wheels, however, high tensile stresses were found in plates. Axle compressive residual surface stresses were produced by water quenching after tempering. High residuals produced by cold rolling of wheelseats were reduced subsequently by surface grinding.
