Optimization of a hydroforming process to realize asymmetrical aeronautical components by FE analysis

Hydroforming process is an effective method for manufacturing complicated parts. This process is quite sensitive to the characteristics of the pressure growth laws and the friction between the sheet and the elements of the tooling. In this work a numerical simulation has been carried out using the explicit finite element code LS-DYNA
with the purpose to optimize a hydroforming process related to the achievement of an asymmetrical aeronautical component. In particular, the number of the steps of the manufacturing cycle actually used to produce the component has been reduced considering the FEM results.

Which can the advantage?

Hi,
since hydroforming process is rather fast, which can the advantage be in the reduction from four to three step in the cycle under examination?

Hi Minutolo and collegues,

There are 1 paper at IPROMS 2006 - Concurrent Engineering section related to FEA. You may have a look at the paper as well as the discussions. Click to the following title to get it:

Dear Antony, thank you for

Dear Antony, thank you for the question.
The main advantage consists in the potentiality of the FEM that has allowed to forecast the success of the new cycle. In this way, it is possible to carry out the design of cycles relevant also to new products, with the optimization of process parameters, avoiding, meanwhile, waste of material.
