WROUGHT WHEEL DESIGN FOR HEAVY AXLE LOAD UNIT TRAINS

The application of finite element analysis techniques permits the determination of both thermal and mechanical stress distributions in a heavy axle load unit train wheel design. Residual stress levels, which are dependent on wheel design and heat treatment, must be analyzed by experimental methods, as these stresses dominate the service stress distribution in the wheel. Residual stress levels also directly affect both crack growth rates and critical defect size. Fracture toughness levels can be improved by attention to steelmaking and heat treatment techniques to give enhanced performance of the high carbon wheel material.
