Ulf Sandberg
Adjunct Professor in Tyre/Road Noise
Swedish Road and Transport Research Institute (VTI)
and Chalmers University of Technology
Prof Sandberg, born 1946 in Visby, Sweden, obtained an MSc degree in electro-technical engineering at Chalmers University of Technology in 1972, a TechLic in measurement technology at Linköping University of Technology in 1984 and an ScD at the same place in 1987. His thesis work was on "Tire/road noise - Studies of the mechanisms of noise generation, methods of measurement and road surface characterisation". After his MSc exam in 1972, Sandberg worked two years at the Linköping University of Technology, until in 1974 he began to work at VTI, which he still does. The original task at VTI was to build up a competence in traffic noise, in particular tyre/road noise.
Over the years, Prof Sandberg has worked with various matters of tyre/road noise, with emphasis both on tyres as well as on road surfaces. However, he has also worked with various aspects of vehicle noise and road traffic noise in general. In 2002, Sandberg was appointed Adj Professor in tyre/road noise at the Department of Applied Acoustics at Chalmers University of Technology and currently works part-time there.
Prof Sandberg is the Convenor of three ISO working groups on noise-related standardisation topics, presently being responsible for five published ISO standards, and a member of some other ISO groups as well as of CEN/TC 227/WG 5. He is leader of two Work Packages of the ongoing very large SILENCE project. Prof Sandberg is presently also serving as a noise specialist consultant in projects in USA and Hong Kong.
In 2002, Prof Sandberg, together with long-term colleague Prof Ejsmont in Poland, published the comprehensive Tyre/Road Noise Reference Book, which has since become the ”Bible” of this subject.

Nicola Gramegna have completed technical study at Padova University with specific
works/experiences on numerical methods for engineering application (FEM, FDM, …) and on
development of dedicated computer programs.
In 1995 he joined ENGINSOFT S.p.A and became responsible of simulation foundry group.
Today he organizes activities of technical team dedicated on process simulation (casting,
forging, injection moulding, forming, machining, heat treatment, etc ) in order to offer
consulting and training devoted to Design Chain solutions and Optimisation.
His experience in metallurgy, manufacturing processes (in particular foundry process) and
mechanical component design is the background to manage European Projects focused on
industrial research in automotive field like the new project NADIA where ENGINSOFT is
the co-ordinator (or the previous projects: Irewo, Coprofound, Metro, IDEAL).

ABSTRACT
The advanced material and the technology innovation in manufacturing processes are undoubtedly the basic research to improve the performance of automotive components as well as aerospace applications.
EU vehicle production and forecasts show a positive tendency in the next years with particular attention to the car weight reduction, high-performance and low consumption. The global market competition forces toward an improvement in quality and efficiency.
Most of the previous European projects and the main FP6 projects actually in progress (e.g. NADIA) are making concrete improvement in materials and processes using a scientific approach combined with CAE tools.
The design evolution of the automotive components is taking to the extremely complex shape with high-performance demand and narrow margin of errors. A Design Chain approach, based on simulation tools for metal casting processes and mechanical behaviour, can provides some positive solutions if the complete virtual loop takes into account all manufacturing phases (e.g. casting, heat treatment, machining etc.) as material mechanical properties depend on.
The traditional manufacturing processes have to be optimised using the well known light materials, while the technology innovation can improve the application of advanced materials. The CAE tools should follow the same evolution in order to support the design and the optimisation during the virtual prototyping phase.
