EXPERIMENTAL VERIFICATION OF COMPUTER-PREDICTED TEMPERATURES AND ELASTIC THERMAL STRAINS IN RAILROAD WHEELS
A dynamometer verification of computer-predicted elastic thermal strains has been done. A 33-inch (845 mm) diameter wheel of the latest Abex design and a composition brake shoe were run on the dynamometer to develop temperature distributions and strains. Computer models were run based on these inputs and successful correlations of temperatures and strains were developed. Such verification allows increased confidence in computer models to accurately assist in railroad carwheel design.
