WALVOIL AT THE 74TH ATI NATIONAL CONGRESS, MODENA, ITALY

Walvoil attended the 74th National Congress promoted by ATI (Italian Thermotechnical Association) and Modena and Reggio Emilia University, whose focus of the year was on ‘Energy conversion: research, innovation and development for industry and territories’.

The congress ended on September 13th in Modena, Italy.

For three days it brought together over 300 delegates from the academic and industrial world, institutions, designers and researchers into plenary and parallel sections. The congress, a unique opportunity for exchanges and meeting, offered a meaningful picture of the state of research in Italy on all the themes dedicated of energy. Five thematic sessions dedicated to Energy conversion were developed: Energy, Internal combustion engines and sustainable mobility, Hydraulics, Turbomachines, Miscellaneous.

Walvoil, with the presentation of Davide Mesturini, R&D Director, contributed to the ‘Research & Development - From the laboratory to the future market’ section with the visions and trends developed by the company. With the one illustrated by Antonella Bonavolontà, University of Naples 'Federico II' Department of Industrial Engineering, the paper dedicated to 'Comparison of Energy Saving and Recovery Systems for Hydraulic Mobile Machines' was presented. This was carried out in partnership with Cesare Dolcin, Test Departmental Manager at Walvoil, Pietro Marani, CNR-Imamoter, Emma Frosina and Adolfo Senatore, both from the Department of Industrial Engineering, University of Naples 'Federico II'.

The paper will be published in the AIP (American Institute of Physics) Conference Proceedings.

Below the ABSTRACT:

The problem of energy efficiency is becoming an essential issue in the design of mobile machines with more restrictive emission legislations to come. To tackle these issues, it is necessary to consider the machine as a whole taking into account the losses from the power source up to the actuators. In the paper, different architectures performing boom function in a midi excavator will be simulated in Simcenter AMESim environment and compared to highlight the energy performance. Different architectures will be considered ranging from Conventional Load Sensing, to Load Sensing with variable pressure margin, to various regeneration and recovery systems.
