QUALITY ASSESSMENT AND KNOWLEDGE TRANSFER In our opinion, an assessment of the quality and quantity of the results and effects achieved by a Competence Centre like charmec should take the following points into consideration: 10 The ability to understand, formulate and “make scientific” the current problems and aims of Trafikverket and the Industrial Interests Group The ability to initiate and run general future-oriented projects within the Centre’s field of activity The publication of scientific works in recognized international journals The publication of read papers in the proceedings of recognized international conferences The conferring of Licentiate and PhD degrees and the appointment of Docents (see page 106) The transfer to Trafikverket and the Industrial Interests Group of information about the results achieved and the implementation of these results at their sites The development, nationally and internationally, of the role of the Centre as a partner for dialogue, as an information hub, and as a network builder During Stage 6, the scientific quality of charmec’s research results has been assured through public presentation and criticism at national licentiate seminars and defences of doctoral dissertations, through the presentation of papers Dynamic forces Fatigue impact FIERCE – evaluation of surface and subsurface fatigue initiation Detailed FEsimulations – surface fatigue initiation, small crack propagation, profile deterioration, etc at recognized international conferences and the publication of papers in recognized international journals. The relevance of our research has been secured through discussions at Board meetings, at seminars at Chalmers with Trafikverket and the industrial partners, and during frequent visits, including brainstorming sessions etc, to industrial sites. Our participation in worldwide railway technology congresses, conferences, symposia, workshops and seminars has also contributed to the calibration of charmec’s research. The transfer of knowledge to Trafikverket and the industry has taken place by means of networking and staff exchanges, through orientation and summarizing at seminars, and through informative <strong>report</strong>s and the handing over of test results and computer programs. An important part of this knowledge transfer is the employment of people with a Licentiate or PhD degree from the University at Trafikverket or in the industry, either directly or through consulting companies. Most long-term research projects within the Centre should correspond to five years of work towards a doctoral dissertation. This work should be formulated in general terms with regard to orientation and goals. A detailed specification of each step of a project (such as when an agreement is drawn up for ordering project work or when consultancy services are purchased) should generally be avoided in an academic environment. DIFF3D – high frequency dynamic simulations MBD-model – low frequency dynamic simulations Wear modelling – surface damage of rails and/or wheels Integration of research results from the <strong>CHARMEC</strong> projects. For DIFF3D and FIERCE, see projects TS4 and MU9 on pages 16 and 43
PROGRAMME AREAS ChARMEC STAGE 6 According to the Principal Agreement for Stage 6, the Competence Centre charmec should work within six overall programme areas as set out below. The choice of projects within each area is decided by the Board of the Centre. These program areas are the same as those during Stages 3, 4 and 5. Programme area 1 Interaction of train and track (Samverkan Tåg/Spår, TS) A rolling train is a mobile dynamic system that interacts, via the wheel/rail interface, with the stationary track structure, which in turn is a dynamic system. This interaction is a key area within all railway mechanics research. The mechanisms behind vibrations, noise and wear depend on the interplay of the rolling train and the track structure. The activities of this programme area are directed towards being able better to understand, model and predict the dynamic interaction for different types and conditions of trains, tracks and operations. Analytical, numerical and experimental methods are used. Programme area 2 Vibrations and noise (Vibrationer och Buller, VB) A considerable reduction in vibrations and noise from railway traffic seems to be of crucial importance to the future acceptance of this type of transportation. The generation and spread of vibrations in trains, tracks and environment and the emission of noise are phenomena that are difficult to approach, both theoretically and experimentally. The activities in this programme area are directed towards achieving a better understanding of the underlying mechanisms. Advanced analytical and numerical tools and well-planned laboratory and field experiments and measurements are required. The goal is to establish a basis for effective modifications and countermeasures against vibrations and noise in trains and tracks and in their surroundings. Programme area 3 Materials and maintenance (Material och Underhåll, MU) Suitable and improved materials for axles, wheels, rails, pads, sleepers, ballast and embankments are a prerequisite for good mechanical performance, reduced wear, lower maintenance costs and an increased technical/economic life of the components mentioned. The activities in this programme area are directed towards analysing existing materials and developing new materials. A knowledge base should be created for the rational maintenance of train and track components. Co-operation between several different competences are required for this research. Programme area 4 Systems for monitoring and operation (System för övervakning och Drift, SD) Brakes, bearings, axles, wheels and bogies are important mechanical components of a train with regard to its operational economy and safety. There seems to be considerable potential for improvement for both passenger and freight trains. New components and new ways of improving and supplementing existing functions should be studied. A systems approach is emphasized and the work is performed in a cross-disciplinary environment, drawing on several different academic and industrial competences, including solid mechanics, machine elements, signal analysis, control theory, and computer engineering and mechatronics. Programme area 5 Parallel EU projects (Parallella EU-projekt, EU) During Stages 1 to 6, Chalmers University of Technology has been a partner, through charmec, in several eu (European Union) projects in railway mechanics within the Fourth, Fifth, Sixth and Seventh Framework Programmes. All these projects are closely related to charmec’s ongoing research in programme areas 1, 2, 3 and 4. charmec contributes to the funding of these eu projects. It should be noted that the legal entity signing eu contracts on our behalf is Chalmers University of Technology. Programme area 6 Parallel special projects (Parallella specialprojekt, SP) At a meeting on 10 September 2002, the charmec Board decided to gather and list a number of our bilateral agreements and separate research and development projects in railway mechanics under the above heading. This programme area includes both short-term and long-term projects, several of which have been established for the industrial implementation of charmec’s research results. 11
