Wheel-Peeling Experiment: Analysis of Commuter Rail Wheel Thermal Cracks

摘要

The report outlines the procedures used and presents the data obtained during thewheel peeling portion of the Cracked Wheel Investigation. The procedure was conducted by ORX, Inc., Tipton, Pennsylvania from April 6 to April 9, 1992. Its purpose was to measure and record the physical characteristics of thermal cracks present in two, selected, railroad wheels. These wheels had been removed from routine service on New Jersey Transit Rail Operations, (NJTRO). Various measurements were taken to describe the thermal cracks in these wheels, both on the tread surface as well as in the rim bulk. Annotated test data were gathered and forwarded to the Volpe National Transportation Systems Center (VNTSC) for analysis in conjunction with the overall investigation of wheel cracking phenomena occurring in commuter rail wheels sponsored by the Federal Administration.
