Infrared Temperature Measurements of a Reciprocating Seal TestA system has been developed to perform a computer analysis on surface temperature data in tribological systems, taken by an infrared radiation scanning device. The infrared scanner which normally scans at 25 fields per second and 100 lines per field has been modified to scan any single line at 2500 lines per second. The system was used to analyze four friction experiments as part of a thermal behavior study of Stirling engine seals in cooperation between Georgia Institute of Technology and Mechanical Technology, Incorporated. The friction experiments involved two tribo pairs, Rulon on steel and Rulon on sapphire. The results clearly demonstrate the importance of the relative rate of cooling and the mechanical cycle time of the system. For rapid mechanical cycle times in the friction experiment the surface temperature distribution reflects the distribution of energy input on the surface and the temperatures persist for periods longer than that of the mechanical cycle.
