Abstract: The present disclosure relates to a method and system for measuring flatness and degree of sea gull in an aluminum alloy sheet continuously moving in a horizontally floating state through a continuous convection floating furnace. The method and system utilize two or more sensors that take readings indicative of flatness as the aluminum alloy sheet continuously moves through the continuous convection floating furnace. These readings may be compiled into one or more graphics indicative of flatness of the aluminum alloy sheet.

Abstract: A tribological testing simulator includes a base having a pair of catchers that clamp onto a specimen, a punch that is drawn through the specimen, and a plurality of sensors that take measurements of respective regions of the specimen. The sensors measure their respective regions of the specimen as it is drawn from an un-deformed state to a deformed state, and facilitate conducting a tensile strip friction test. In some embodiments, the catchers have flat inserts that facilitate conducting a strip stretch or draw test simultaneously with a tensile strip friction test. In other embodiments, the catchers include drawbead inserts that facilitate conducting a drawbead friction test simultaneously with a tensile strip friction test.
