Abstract:Hydraulic systems that are operated outdoors during winter can be exposed to extreme low temperatures. Low temperature thickening of the hydraulic fluid can increase power consumption, cause pump cavitation, and stall system actuation. In this study, the response time and power consumption of a hydraulic vehicle restraint system that is used outdoors year-round was evaluated at low temperatures. This safety device incorporated proximity switches that triggered a machine “fault” when the time delay between the … 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.
