Conference

A numerical model for the evaluation of gerotor torque considering multiple contact points and fluid-structure interactions

Autor: Mistry, Zubin, Manne, Venkata Harish Babu, Vacca, Andrea, Dautry, Etienne, Petzold, Martin

This paper presents a numerical model for the evaluation of the actual torque in Gerotor units. The model consists of two major modules: the pre-processor module and the HYGESim module. The preprocessor module consists of the geometric and the mechan

Conference

A fast approach for coupled fluid-thermal modeling of the lubricating interfaces of axial piston machines

Autor: Mukherjee, Swarnava, Shang, Lizhi, Vacca, Andrea

The temperature distribution of the lubricating interfaces is an important aspect of the functioning of positive displacement machines. It can determine the efficiency and the life time of the unit. In particular, it directly affects the fluid proper

A closed circuit electro-hydraulic actuator with energy recuperation capability

Autor: Qu, Shaoyang, Fassbender, David, Vacca, Andrea, Busquets, Enrique, Neumann, Uwe

The recent electrification trend in the off-road market has incentivized research towards the proposal of compact, cost-effective and energy-efficient solutions for hydraulic actuators. As a result, increased attention has been given to electro-hydra

A Flow Control System for a Novel Concept of Variable Delivery External Gear Pump

Autor: Vacca, Andrea, Devendran, Ram Sudarsan

Publikováno v: 10th International Fluid Power Conference (10. IFK) March 8-10, 2016. 2:263-276

This paper describes a novel concept for a low cost variable delivery external gear pump (VD-EGP). The proposed VD-EGP is based on the realization of a variable timing for the connections of the internal displacement chambers with the inlet and outle

A General Method to Determine the Optimal Profile of Porting Grooves in Positive Displacement Machines: the Case of External Gear Machines

Autor: Gulati, Sidhant, Vacca, Andrea, Rigosi, Manuel

Publikováno v: 10th International Fluid Power Conference (10. IFK) March 8-10, 2016. 1:453-464

In all common hydrostatic pumps, compressibility affects the commutation phases of the displacing chambers, as they switch their connection from/to the inlet to/from the outlet port, leading to pressure peaks, localized cavitation, additional port fl

A Lumped Parameter Approach for GEROTOR Pumps: Model Formulation and Experimental Validation

Autor: Pellegri, Matteo, Vacca, Andrea, Devendran, Ram S., Dautry, Etienne, Ginsberg, Benjamin

Publikováno v: 10th International Fluid Power Conference (10. IFK) March 8-10, 2016. 1:465-476

This paper describes a high fidelity simulation model for GEROTOR pumps. The simulation approach is based on the coupling of different models: a geometric model used to evaluate the instantaneous volumes and flow areas inside the unit, a lumped param
