Abstract
Hydroforming allows to overcome some of the limitations of conventional deep drawing, increasing the drawing ratio and minimizing the thickness reduction of the moulded parts. Among the advantages introduced by hydroforming there is a great flexibility and a remarkable reduction of the tooling costs. The key parameters of the process are the hydrodynamic pressure laws and the friction coefficients in the different zones of contact between the sheet and the elements of the tooling. Several researches in such a field evaluated these parameters in order to find the optimal values for a correct carrying out of the manufacturing. A numerical simulation was carried out using the explicit finite element code LS-DYNA with a view to optimizing a hydroforming process related to the manufacturing of an asymmetrical aeronautical component, currently produced at the Avio S.p.A. plant of Pomigliano d'Arco (Naples-Italy).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
