Abstract
The magnitude of mechanical vibration and noise generated within machinery depends on damping. However, little is understood about how damping is distributed among the various possible damping sources. The results given in this paper isolate and quantify lubrication film damping between rolling discs and show that damping within the lubrication film contributes significantly to the total damping. A comparison of laboratory measurements with computer calculations shows that lubrication film damping is greatest under conditions of contact separation and thus indicates that fluid film damping is generated primarily by the squeeze film mechanism.Keywords
