In virtual simulation of product performance, the methods used to
simulate aerodynamic, ergonomics and biomechanical
performance were extended and improved.
As part of its work to improve vehicle service, Elasis developed an
inter-Sectorial method for analyzing maintainability and generating
service documentation that will help determine optimal
disassembly sequences and improve the quality of repair manuals
and owner’s handbooks.
In the area of processing methods, Elasis continued its work with
virtual manufacturing, developing methods and tools for
ergonomic analysis and for optimizing workstations in a virtual
environment.
■Vehicle research. Vehicle research work concentrated on the
Alfa 8C - Competizione project and development of the new
Fiat Fiorino. In developing the Alfa 8C Elasis followed up on
the experience it gained in building the prototype for this car in
2004. To streamline the development process, Elasis employed
a virtual approach. Elasis also introduced innovative
steel/carbon fibre body shell technologies. For the new Fiat
Fiorino, Elasis worked together with Tofas to develop body
shell systems, closure panels, interior and exterior trim, wiring,
body computer, and body packaging.
■Electronic control systems. Together with the Centro Ricerche
Fiat, Elasis developed a driveability simulation method that
allows for an evaluation of a vehicle’s handling performance
during the manoeuvres called for by Fiat test standards.
Hardware-In-the-Loop systems were developed together with
automated procedures for testing the self-diagnostics software
used in electronic engine management, ABS and ESP system
control units. For Magneti Marelli Electronic Systems, Elasis
validated the software for a number of body computers. For
the Ferrari Manufacturing Division (Gestione Industriale),
Elasis updated the Hardware-In-the-Loop vehicle dynamics
simulator used to test the electronic control unit for the Delphi
Magneride active suspension system based on innovative
dampening fluids. Elasis also provided support in developing
the control system for the new dual clutch transmission. For
CNH, the centre continued in 2007 to provide support in
validating the control software for the CVT transmission
featured on the Cobra tractor, and began development of a
simulator for CNH which will be used to validate the electro-
hydraulic drive control system on the equipment maker’s
Grader vehicle.
■Fire engines. Elasis assisted in production startup for the
FIRE T-Jet engine and in the launch of the Bravo 150 HP T-Jet,
Grande Punto 120 HP T-Jet and 120 HP Linea cars. For the T-Jet
powerplant, Fiat Group Automobiles’ first application of the
downsizing concept, Elasis developed the initial concept and
was also responsible for design and testing. This engine served
as the basis for developing the high-power 180 HP, 270 Nm
version for the Punto Abarth Esseesse. Development and
product engineering work was also completed on the Fire 8
and 16 valve versions for the Fiat 500, Fiat Group Automobiles’
first application to comply with Euro 5 emissions regulations.
Development and product engineering work is now under way
on naturally aspirated and turbocharged version of the new 1.4
litre Multiair engine, which uses an innovative intake valve
control technology to improve performance and fuel economy.
In addition, Elasis is working together with the Centro Ricerche
Fiat in developing and validating the two-cylinder spark
ignition engine, as well as in product engineering for this unit.
