Abstract

The characteristics of a thermal asperity sensor for detecting slider/disk asperity contact were investigated. A thermomechanical finite element model was used to determine the temperature change of the thermal asperity sensor while sliding against a disk asperity. The effect of sensor size and operational temperature, disk asperity material properties, and contact conditions were investigated.
