European Projects

TRANSVALOR has always been, in association with the CEMEF, an active participant in numerous projects funded by the European Commission. Some of the most significant technological advances of the latest years have come from these research programs.

RINGING - from 2004 to  2008

Novel environment integrating process design and control for ring rolling of net-shape complex profile products
Partners: SNR Roulement, Hot Roll, Univ di Padova, Universita di Roma Tor Vergata, Cemef,  Transvalor

Annular component produced either by ring-rolling or similar processes are usualy critical structural parts. Compared to forged rings, rolled rings are often of superior quality as the process assures favorable grain flow. The main drawback is that often, due to out-of-roundness, conicity or waviness, 30% of the material is wasted.
To address this issue, in this project, both  numarical and experimental tools are going to be developed or improved in order to make possible a real optimization of the process. In this project, Transvalor specifically focus both and actual description of the dies kinematics as well as the Cpu time reduction.

IMPRESS - from 2001 à  2004

Improvement of Precision in Forming by Simultaneous Modelling of Deflections in Workpiece-Die-Press System
Partners: Cemef, Buurskov & Maskinfabrik, D.T.U., Iskra Avtoelektrika , Padova University, Smetek, Transvalor, Vaccari

Non symmetric conditions causes eccentrics loads on the press resulting in additional horizontal forces, bending and often torsional movements on the press frame. This results in different horizontal displacements between upper and lower die leading to loss of accuracy and furthermore life press decrease.
The goal of this project is to include the die/press deflection within FORGE3.

BLANKSIM - from 2000 à 2002

Blanking simulation
Partners : DOISTUA S. A., GSB FORJA, LABEIN, TRANSVALOR

The goal here is to be able to simulate the blanking process. To achieve this, it is not only important to compute the cutting of the material but a special care has to be given to the precision of the elastic recovering after the trimming.
Thanks to the unique fully elasto-plastic implementation of FORGE3 and its adaptative remeshing capabilities, users will have access to a really predictive blanking simulation package after the project will be finished.

FORSYS - from 1998 à 2001

A New Type of Press for Hot and Cold Forging Processes
Partners : CEMEF, CIMSI, ERGO TRONIC, FICEP, TRANSVALOR

The object of the FORSYS project is to develop a new range of presses for both hot and cold forging. The development of these machines is being performed using FORGE2 and FORGE3 computations in order to optimize their use in real-life situations.
TRANSVALOR is closely associated not only to development of the presses design and use, but also to their commercialisation: press buyers will be offered the possibility to buy a dedicated version of the FORGE2 package in order to take full advantage of their new tool.

EFFORTS - from 1997 à  2000

Enhanced Framework for Forging Design using Reliable Three-Dimensional Simulation
Partners : CEMEF, D.T.U., DELCAM, K.T.H., RAUFOSS, SIFCOR, TA.A Hydronics, TEKSID, TRANSVALOR

The goal of this project was to improve rheological and friction models with respect to the forging process, in order to improve the accuracy of simulation results.
These new and more precise models have been integrated into FORGE3 as soon as they became available.

WINPAR - from 1997 à 1999

Windows based parallel computing
Partners : CEMEF, DASH ASSOCIATES, GENIAS, GMD, SIMULOG, U COIMBRA, U. VIENNA, TRANSVALOR

Within the WINPAR project an integrated software development environment for parallel computing targeting PC's connected by local networks or multi-processor PC's (Xeon, ...) running under WINDOWS NT has been developed.

This project has allowed TRANSVALOR to achieve a parallel version of FORGE3 running on personal computers. This version is now available to our customers.

DRAMA - de 1997 à 1999 Dynamic Reallocation of Meshes for Parallel Finite Element Applications

Partners : CEMEF, E.S.I., N.E.C., K.U.Leuven and TRANSVALOR

The DRAMA project objective is to develop an application programming technology which will allow complex industrial simulation codes such as FORGE3 to progress beyond the use of static mesh partitioning to dynamic load balancing.
This project will give to TRANSVALOR the necessary technology to increase the number of processors used effectively in the parallel version of FORGE3 (a reasonable limit is currently eight processors).
