National Projects

Closely related to the Ecole des Mines de Paris, a leading french engineering university, TRANSVALOR is naturally often implicated in research projects at the french national level, with numerous large-scale industrial participants. From these projects, TRANSVALOR has not only gained technological benefits, but also a deep insight on industrial needs and constraints.

Partners :  TRANSVALOR /ASCOMETAL CREAS / ARMINES / GEVELOT EXTRUSION / ATELIERS DE LA HAUTE GARONNE / INDUSTEEL / SETFORGE / TREFIL EUROPE / BOLLHOFF OTTALU / CETIM / FORGES DE COURCELLES /ATELIER DES JANVES

MONA LISA - from 2007 to 2010

The Monalisa project was initiated in early 2007. It aims to supply an effective solution for sizing fastening systems.

The theoretical principle is to apply a loading condition onto the fastener taking in account the eventual stress distribution due to prior stages. The project focused initially on process like riveting, screwing, clinching.

The project involves three main partners : the Cetim providing deep knowledge of the process, the Cemef/MinesParistech providing well-established scientific expertise and Transvalor as fully-recognized software editor dedicated to mechanical engineering and material processing.

Partners :  CETIM / ARMINES CEMEF / TRANSVALOR

OPTIFORGE - from 2006 to 2009

Integration of set up stage in the proportioning of forged indutrial parts.

Partners : ARMINES / ASCOMETAL /ASCOFORGE SAFE / INSA DE LYON / PEUGEOT CITROEN AUTOMOBILES / SERAM /SETFORGE / TRANSVALOR / CETIM

OPTIMAT - from 2002 à 2005

Optimisation of processes of material transformation - RNTL project

Partners : CEMEF, ENSAM Angers, Institut Supérieur de la Conception (associated to UTC), ENSMP Besançon, MECALOG, TRANSVALOR and DEVILLE S.A., AUBERT ET DUVAL, AMIS-SIFCOR, PSA

Project OPTIMAT aims to help to design products with determined properties, as well from the geometric point of view as from the microstructural point of view, or its properties in service.

Numerical techniques of optimization coupled with simulation software of material forming will be used.

SIMULFORGE - from 2001 à 2005

The SIMULFORGE project, developped by the CETIM , gathers sixteen forging companies and TRANSVALOR with the following three main objectives:

1) To enlarge the scope of the simulation in order to be able to simulate the whole manufacturing project (heating, forging, blanking, cooling, heat treatment).
2) To be able to predict the metallurgical status of the part at the end of the manufacturing.
3)To disseminate the use of the forging simulation among SME’s.

To achieve the two first goals, twenty PhD or Post-Doctoral studies are going to be launched in six different laboratories. A specific care is given to heat treatment, trimming and rupture simulation.
The third point has been addressed by completely redesigning the Graphical User Interface using the concept of virtual forging shop.

OSC - from 2000 à 2004

Optimisation des systèmes de coulée en fonderie
Partners : Aubert & Duval, Creusot-Loire Industrie, CTIF, Erasteel, PSA, Fonderie de l'Atlantique, Cemef, LSG2M (Ecole des Mines de NANCY), L3S (Ecole polytechnique de GRENOBLE), TRANSVALOR

The OSC project gathers casting companies, research laboratories and Independent Software Vendors including Transvalor.
Within this project the existing 3D FEM software THERCAST which is already able to compute the coupled thermomechanical analysis of the metal cooling in a set of dies will be completed by a filling module.
In order to better predict the quality of the final part, metallurgical segregation and defect prediction will be added in both filling and cooling modules.

ACR2 - from 1996 à 2000

Action concertée de recherche
Partners : ASCOFORGE Estamfor, ASCOFORGE Safe, AUBERT & DUVAL, CEMEF, CETIM, CEZUS, C.L.I., ECOLE DES MINES Albi, ECOLE DES MINES Nancy, ENSAM Angers, FORTECH, GIAT, INSA Lyon, IRSID-CREAS, ISITEM Nantes, LYCEE Marie CURIE Nogent, MANOIR Industries, PSA, RENAULTS SA, RENAULT V.I., SETFORGE, SIFCOR, SNECMA, SNR Roulements, TRANSVALOR, U. VALENCIENNES

The goal of the ACR2 project is to develop and industrialize numerical modelling tools to simulate the forging of arbitrarily shaped parts. This action is taken in order to favor the evolution of the trade towards a key technology which can provide an objective insight on the major mechanisms involved in forging.
TRANSVALOR products have greatly been enriched by the participation in this project. Specific industrial needs are fulfilled within this large framework and integrated in our software.

GPI Fonderie - from 1995 à 1999

Grand projet innovant
Partners : ASCOMETAL, AUBERT & DUVAL, CEMEF, C.L.I., INPG L3S, INPL, PSA, S&CC, SERAM, TRANSVALOR

As its name suggests, this project has an innovative goal. The subject is the study of the simulation of the foundry process.
Within the scope of the project, three existing software, namely R2, SOLID and THERCAST, were to be improved and merged into one industrially usable 3D simulation tool of both the filling and cooling stages of the foundry process.
