Small Arms Components Motion-Simulator for Lubricant Development: 2. Use in Lubricant Friction Testing

Abstract

A Small Arms Components Motion-Simulator was designed and constructed to establish the performance characteristics of current and future lubricants under extremes of environment. The machine is installed in the Research Directorate, GEN Thomas J. Rodman Laboratory, and has been subjected to tests to determine its capabilities. This report describes the results of these tests. Primarily, the simulator imparts linear motions on the basis of time- displacement characteristics of the XM19 Bolt, M85 Machine Gun Bolt, M219 Machine Gun Barrel Extension and Rammer, and the M129 Grenade Launcher Barrel to a test specimen through which contact is made with a stationary specimen. The motions are obtained from an adjustable constant speed drive and cam system. Friction forces generated by the rubbing surfaces are transferred to a load cell and recorded on an oscillograph.
