BREAQ
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.
Detail
In fact, reducing fine particle emissions (PM10, PM2.5) as well as the consumption of trains by aerodynamic means has become a major environmental and public health issue. The BREAQ project, of which lamih is one of the contributors, aims more explicitly at predicting and reducing fine particles emissions induced by contact friction (braking) and this from their generation to their transport (coupling emission/diffusion of particles). Indeed, the emission of particles or VOC (volatile organic compounds) in the close environment during braking is linked, on the one hand, to the thermomechanical solicitations at the lining - disc interface, and on the other hand, to the space under the vehicle which will influence their initial trajectory. At the stage of the study of the emission, it is advisable at the same time to be interested in the parameters influencing the quantity and the size of the particles but also on their privileged trajectory of evacuation and the influence of the environment. The final goal in the long term consists in being equipped with innovative tools of prediction/control of the environmental impact of the railway rolling stock (subway, regional train, 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 modeling (WP3) and reduction of environmental impacts by capture and regulation of the brake control (WP4).
