Abstract

A semianalytical finite element method was employed for analysis of railroad car wheels. The accuracy of the computational model was estimated by comparing the numerical results with analytical solutions for a simplified wheel model and with tensometric data. Innovative wheel designs were developed and subjected to full-scale tests. The wheels were rolled following computer-assisted engineering of the new designs. Their advantages over conventional wheels were validated by operational tests. 1 Introduction Designing railroad car wheels necessarily involves analysis of the state of stress and strain in appropriate models. Clearly, a wheel in service is subjected to a great multitude of diverse external factors of mechanica
