Variable displacement hydraulic machines offer a very promising alternative and energy saving solution for many applications in mobile machines, robots and other applications. In the present paper a vane pump will be theoretically analyzed using the software AMESim and/or MATLAB/Simulink, in order to estimate the friction forces and volumetric efficiency loss without hardworking experimental tests. The friction forces taken into account by our model are the friction between vanes and rotor slots and that between vanes and eccentric pump stator. The same design parameters affect the volumetric and mechanical efficiency, whose behavior has been reported and discussed. The behavior of the machine is analyzed and discussed at different angular velocities and pressure regimes.

Abstract
Variable displacement hydraulic machines offer a very promising alternative and energy saving solution for many applications in mobile machines, robots and other applications. In the present paper a vane pump will be theoretically analyzed using the software AMESim and/or MATLAB/Simulink, in order to estimate the friction forces and volumetric efficiency loss without hardworking experimental tests. The friction forces taken into account by our model are the friction between vanes and rotor slots and that between vanes and eccentric pump stator. The same design parameters affect the volumetric and mechanical efficiency, whose behavior has been reported and discussed. The behavior of the machine is analyzed and discussed at different angular velocities and pressure regimes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
