WP01 - TOP LEVEL REQUIREMENTS The objective is to understand, specify, agree and update top-level specifications for traction systems from Roll2Rail with the operational and maintenance needs of operators to secure train operator needs for the year 2020 and beyond. With these inputs, the top-level requirements of the next generation traction systems will be described for a range of applications covering tramway, metro, sub-urban, regional and high-speed. Market segment specific requirements are developed that serve as input for the traction demonstrators. WP02 - DEVELOPMENT OF LAB PROTOTYPES The main objective of this WP is the development of lab prototypes of innovative Traction components and/or subsystem, at TRL2 to TRL4 levels depending on members’ contributions and prepare the defined future traction systems of IP1 vehicle (TRL7) on train testing. The objectives to be attained in this work package are:
Continue and extend previous developments done in Roll2Rail on Traction systems for tramways, metro, sub-urban, regional and HST taking into account the different respective markets and technical constraints and needs of each segment.
Increase performance and power density of the traction equipment to contribute to a higher system capacity. The reduced volume of the traction system supports realizing new train architectures with additional potential to increase the number of seats and payload. A higher efficiency of the traction system will decrease the energy consumption and less material used will decrease the capital costs. This will contribute to lower initial and operational costs and thus increases the competitiveness of the railway system.
Increase line capacity by reducing dwell times by using a driven independently rotating wheel architecture.WP03 - TOOLS AND METHODOLOGIES TO REDUCE NOISE AND EMI EMISSION The objective of this task is to develop methodologies and simulation tools able to predict the acoustic noise and EMI emissions during the development phases of the traction system and sub-systems in order to reduce, as a result, the acoustic noise and EMI (Electro-magnetic interference) emission of future traction systems. WP04 - TOOLS AND METHODOLOGIES FOR INCREASED RELIABILITY, AVAILABILITY AND SMART MAINTENANCE The objective of this work package is to increase reliability and availability of the traction system and the related traction components, especially SiC (Silicon Carbide) power modules, sensors and inductive components. The main items to be improved and developed in this task are:
Improve knowledge of mission profiles
Improve knowledge of failure mechanisms of critical power (traction) components
Improve existing methodologies for life cycle estimation of critical power (traction) electronics, especially power modules
Improve methodology of reliability stress test
Improve models for reliability and lifetime prediction
Develop concepts for remote diagnostics and health monitoring
Develop concepts and architectures for higher availability
Develop concepts for predictive maintenance The work in this task will focus on (but it is not limited to) main power critical components, e.g. SiC power modules, sensors and inductive components. WP05 - REQUIREMENTS, SPECIFICATIONS AND DEVELOPMENTS FOR VIRTUAL VALIDATION AND CERTIFICATION The main objective of this work package is to contribute to a reduction of Rolling Stock capital costs by developing methods and simulation tools/methodologies which would enable a significant reduction in the number of traction component and system validations, homologations and physical test certifications. WP06 - SUPPLY STANDARDISATION FOR KEY COMPONENTS & TECHNOLOGY TRANSFER The objective is to deliver pre- standardization for key components (like semiconductors) and key technologies (like predictive maintenance, virtual certification) including an update of the relevant new technologies as well as access and transfer research results from on-going and forthcoming European research projects out of different industries, and also from research programmes outside of Europe..WP07 - ADHESION DETECTION AND LOW ADHESION MANAGEMENT The objective of this work package is to map different adhesion conditions occurring in rail traffic. With the resulting adhesion catalogue, predictions to adhesion conditions dependant on seasonal influences and locations can be given. This data collection is the basis for a standardized adhesion detection concept. WP08 - ADHESION MODELING AND LABORATORY & TRACK REPRODUCTION SYSTEMS The main objective of this WP is to specify and realise a WSP (Wheel Slide Protection) test bench demonstrator based on the results of WP7. Test bench design objectives are:
Reproducibility of test results.
Reproducibility of real track test results.
Standardized interoperable test method and reporting.
Reduce the number of track tests needed for certification of WSP systems.
Proposal for EN, UIC, etc. standards up to date to promote standard test rigs for WSP certification Within the work package objectives, an adhesion model will be developed to better reproduce in laboratory the real low adhesion conditions happening on track. Based on the adhesion model standard test benches will be defined for the realisation of approval tests for low adhesion management systems, e.g. friction and/or electrical wheel slide protection WP09 - PROJECT MANAGEMENT AND TECHNICAL COORDINATION WP10 - DISSEMINATION, COMMUNICATION AND EXPLOITATION
