ITN - GRESIMO: Best Training for GREen and SIlent MObility (No. 290050)

Engineering for future mobility must be inspired by ecology and economy to enable green and silent vehicles. Current university based education is focusing on classical fields like mechanical engineering on one side with some aspects of Noise, Vibration & Harshness (NVH) and Light Weight Design (LWD) or like electrical engineering covering aspects of “Electrification” & “Hybridisation (H/E)” on the other side.

The GRESIMO project (Best Training for Green and Silent Mobility) aimed to bring together early stage researchers and experienced specialists from across industry and academia in Europe covering NVH, LWD and H/E disciplines to form a broad range of professional background.

Recent research underlines the strong interaction and shows the often conflicting demands of these 3 topics. Consequently, an optimum for future vehicle development requires an interdisciplinary education in this triangle of topics.

GRESIMO focued to motivate and encourage early stage researchers for scientific work in the new interdisciplinary research fields NVH+LWD, LDW+H/E and H/E+NVH. The fellows ware trained and supported in their phase of doctoral thesis to found innovative PhD topics as well as to received specific education in theoretical and practical trainings. The education comprised existing lectures in the partner network as well as training specifically developed for the interdisciplinary needs.

GRESIMO was formed by a group of participating hosts, combining leading education and research institutions as well as industrial enterprises in 6 countries of the EC. Thus the engineers participated in both the scientific research work and the practical application of new methods of testing and simulation. They profited from extended international knowledge after their academic education when starting to work in the industry. Furthermore, the industry will gain from the specific training of the young researchers for the requirements to develop green and silent vehicle.

The general objectives of the GRESIMO project were:
• to bring together early career researchers and experienced colleagues from across Europe, from across NVH, Light Weight Design (LWD) & Hybridisation/Electrification (H/E) disciplines, and from a broad range of professional backgrounds.
• to motivate and encourage early stage researchers for scientific work in the new interdisciplinary fields between the 3 mentioned research areas.
• provides high level education, training facilities and technical supervision for PhD fellows in these new disciplinary fields between NVH, LWD & H/E.
• to support and to train fellows in their phase of doctoral thesis in advanced research methodology.

The support was provided to find relevant and innovative PhD topics.
• to received specific education as well as theoretical and practical training in one or two of the mentioned interdisciplinary fields to the fellows, in order to encouraged scientific work in this area and to enabled top level PhD research.

The description of the main results achieved so far in the GRESIMO project:
• an excellent consortium with high and very active industrial participation was defined.
• an excellent consortium with top universities and research centres was broth together.
• personal carrier development plan (PCDP) were defined for each fellow with his supervisor.
High-level internal and external training events were organised such as (technical workshops, Marie Curie Summer School, public events and complementary skills courses).

Despite the main aim of the GRESIMO project was to train a number of fellows in the field of green and silent mobility, important scientific results have been obtained.
• It is worth to mention the activity carried out by some ESRs in the field of optimization, in view of the conflicting NVH and lightweight requirements. In particular methods to improve the efficiency of optimization algorithms on multidisciplinary problems involving, lightweight design, NVH, and Passive safety requirements have been developed, such that more effective trade of solutions can be found during the development of HEV structures.
• A ray tracing method has been developed and implemented to characterize lightweight, absorbent materials. The main contribution of the research is that an optimization problem has been developed using ray tracing and measurements in order to extract important material properties such as normal surface impedance, random incidence absorption coefficient and oblique incidence absorption coefficient.
• A new approach was adopted to deal with the presence of damping in structures composed of metamaterials. This approach will help to deal with frequency dependant material properties.
• Interesting results has been obtained in the filed of topology optimization results of composite materials.
• Last but not least, significant scientific contribution has been achieved in the area of structural optimization with regards to the fatigue-life criteria.
