A YARD TEST OF ACOUSTIC SIGNATURE INSPECTION OF RAILROAD WHEELS

An earlier laboratory study established the feasibility of using acoustic signatures for inspection of railroad wheels. The present work was undertaken to establish the system's operational capabilities by a period of testing in a switching yard. Tape recordings were made to serve as a data base for finding the algorithm which best distinguished wheel sets with a defective member. Wheelsets whose members exhibited extremely different wear could not always be distinguished from those with a cracked wheel. It is anticipated that when the measure of differential wear on a wheelset has been incorporated in the algorithm its ability to distinguish cracked wheels will be considerably improved.
