This proposal has been developed to tackle the two main challenges related to Traction systems and Adhesion highlighted in the Call text.
The traction sub-project will address these objectives as follows:
- Railway system LCC reduction. Traction system cost reduction by reduction in validation & certification cost via simplification, harmonization of rules and shifting/replacement of “on site” certification experiments by numerical simulation and/or static test bench tests.
- Operational reliability increases via higher reliability/availability of components. Progress on methodologies and tools in these fields, especially in WP4 & WP13, will be applied to new Traction systems developed within the project. The benefit will be a dramatic reduction in the number of In-service failures per million km;
- Train & Line capacity increase through weight, volume and noise savings of Traction equipment. These improvements will permit new train architectures to increase the number of seats and/or passengers' comfort.
The main specific objectives of adhesion management for brakes are:
- Improvement of braking degradation limit in poor adhesion condition
- Management of all adhesion conditions in a way that brake distances are optimized
- Improvement of the overall train safety for braking, which relies substantially on the management of the wheel/rail contact
- Reduction of wheel Life-Cycle-Costs (LCCs) through optimized wheel/rail contact in braking
