BREAQ
Characterization and mitigation of braking emissions to improve air quality
The " BREAQ " project for BRaking Emissions characterisation & mitigation for Air Quality improvement funded by ADEME and led by ALSTOM deals with the impact of rolling stock on its environment in terms of emissions.
In fact, reducing fine particle emissions (PM10, PM2.5) and train fuel consumption by aerodynamic means has become a major environmental and public health issue. The BREAQ project, of which lamih is a contributor, aims more explicitly to predict and reduce fine particle emissions induced by contact friction (braking), from their generation to their transport (particle emission/diffusion coupling). Particle or VOC (volatile organic compound) emissions into the immediate environment during braking are linked, on the one hand, to thermomechanical stresses at the lining-disc interface and, on the other, to the vehicle's overall dimensions, which influence their initial trajectory. The ultimate aim is to develop innovative tools for predicting/controlling the environmental impact of rail rolling stock (metro, regional trains, tgv). The LAMIH (departments of mechanics and automation) is positioned on 3 workpackages of the BREAQ project, i.e. on the themes of particle emission (WP2), particle diffusion modelling (WP3) and the reduction of environmental impacts by capturing and regulating brake control (WP4).
