ABSTRACT: This report summarizes an extensive research program into the causes of wheel thermal failure. Results of material property tests, review of failure data, dynamometer tests, roll dynamics unit, track tests, and theoretical and experimental stress analysis show that heat-treated wheels of designs which meet the requirements of AAR Standard S.660 (low-stress wheels) are significantly more resistant to failure. This volume contains appendices to the report.
