The RUN2RAIL project (Innovative RUNning gear solutions for new dependable, sustainable, intelligent and comfortable RAIL vehicles) will explore an ensemble of technical developments for future running gear, looking into ways to design trains that are more reliable, lighter, less damaging to the track, more comfortable and less noisy. The RUN2Rail project is funded by the Shift2Rail Joint Undertaking under the European Union’s Horizon 2020 research and innovation program under grant agreement no. 777564. The development of a new generation of running gear is pivotal to the achievement of the ambitious goals set by Shift2Rail for future European trains, encompassing the substantial reduction of life cycle costs, improved reliability and energy efficiency, the reduction of noise emissions and of other externalities and the achievement of full interoperability of the rolling stock.
The aim of the RUN2Rail project is to identify and develop the key methods and tools that are required to allow the design and manufacture of this next generation of running gear. RUN2Rail aims at exploring an ensemble of technical developments for the future running gear, by implementing a coordinated set of research activities addressing four Work Streams:
CDH has proudly participated in WP4 and made contributions in following areas
A comprehensive methodology for predicting the transmission of noise and vibration from the running gear to the car body has been developed based on models for both structure-borne and airborne noise transmission. Frequency dependent characteristics of primary suspension elements obtained from laboratory measurements have been studied using an computationally efficient method using a method developed in CDH.
These prediction models have been validated through extensive field measurements carried out at Metro de Madrid into the noise and vibration behavior of a test vehicle. The relative contributions of the different transmission paths have been quantified.
The newly developed models have been used to assess the effect of various changes to the running gear on noise and vibration. In particular an initial assessment has been made of the effect of novel lightweight materials and active suspensions systems and an optimization strategy for controlling the structure-borne noise transmission has been demonstrated.
The research outcome has been presented in the 13th International Workshop of Railway Noise (IWRN13).
