Collection description

The Fluid Power area handles a profound change to achieve the highest efficiency levels requested by the market to compete with other technologies of different fields, like Hybrid-Electric configuration. The noise emission increases its importance in the fluid power field since the other technologies cannot have the same power density, flexibility, and reliability as the Hydraulic. For this reason, hydraulic components, especially positive displacement pumps and motors, are pushing to conform to the dB limits defined by European regulations for working environments (ref. SNSI, Horizon 2020, and Direttiva Macchine 2006/42/CE), both in mobile and indoor applications. The purpose of this research activity is aimed at the optimization of pump geometries using numerical and experimental techniques.
