Abstract

Fluid power (hydraulic and pneumatic actuation) as an integral part of manufacturing and transportation has big impact in real sector of economy. In 2008, according to the U.S. Census Bureau, average efficiency of Fluid Power Systems amounted 22%, while the sales of systems using fluid power exceeded $226B. As large as the industry is, it has had little fundamental research that could lead to improved efficiency since the 1970 energy crisis. While there have been some attempts to improve fluid powered components separately, there has been lack of attention to the societal impact of the whole industry. This article analyzes energy specific measurements (consumption, emissions, efficiency) of current systems from energy perspective and stresses societal impact of improvements proposed from the fluid power research community.
