    • Abstract:
      Twenty-six used and rebuilt solid rubber road wheels were examined by an infrared temperature profiling technique during drum test exercise. The IR method was evaluated as a nondestructive means of predicting road wheel integrity by analysis of the circumferential temperature profile. The effectiveness of the temperature profiling method was determined by stripping the rubber from each wheel and visually evaluating the bond interface and rubber tread. Known defects comprising tread and sidewall cracks and rubber-metal interface delamination were artificially induced into rebuilt road wheels to evaluate the examination method. Left and right sidewall and tread area were examined simultaneously by use of three sensor heads which were mounted in a test rig positioned around the test wheel. Results indicate that the IR TEST TECHNIQUE HAS A CAPABILITY OF DETECTING CRACKS AND CHUNKING IN THE RUBBER TREAD, GROSS UNBONDS AND INTERFACE DELAMINATIONS, AND LARGE AREA ENTRAPPED FOREIGN OBJECTS AT THE RUBBER-TO-METAL INTERFACE. Low bonds strength and small unbond areas less than on square inch were not detected. Defects located along the left sidewall interface area were more difficult to sense due to the wear flange and high thermal coupling into the metal sidewall which dissipated tread developed heat.
