Small Arms Components Motion-Simulator for Lubricant Development: I. Selection of Parameters.

摘要

Seven small arms weapons were examined and studied to obtain information on parameters related to lubrication. A number of significant parameters were tabulated to show what characteristics should be included in the small arms components motion-simulator. Thirteen lubricant testers,available in the Science and Technology Laboratory,were evaluated for use in testing weapons lubricants. Two of these machines,the USAWECOM Friction and Wear Tester,and the Frictionometer provide velocities approaching those found in reciprocating small arms components. A kinetic friction coefficient and durability test was conducted on four weapons lubricants with the use of a Falex Lubricant Tester. Two lubricants, LSA and LSA-T,gave lower friction coefficients and longer durability than the PL-S and LAW lubricants. The friction coefficient of 0.12found for PL-S on steel was the same as a value found earlier on the USAWECOM tester. (Author)
