Abstract:Breech mechanism is the key and important device to improve reliability and maintenance for large caliber guns. It’s major fault mode is grain abrasion caused by dry sliding friction. There is no feasible and practical technologies to simulate and predict the abrasion failure life of key parts for breech mechanism. A new simulation and prediction method is firstly put forward in this paper. Based on Pro/E and ADAMS, the virtual prototype of breech mechanism of semiautomatic vertical sliding-wedge type is estab… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
