【Abstract】 A system for measuring the surface temperature was developed and the transient surface temperature on rotating clutch discs by infrared detection was measured. The transient surface stress in the discs was calculated by the finite element method using the temperature data acquired from the test. The experiment showed that the temperature distribution on clutch disc surface is very uneven. The calculated results present the transient stresses in some areas of the disc are above the yield stress of the material used.更多还原
