Liebherr-Transportation Systems, Grand Central Rail (part of Arriva Group) and NewRail (The Centre for Railway Research at Newcastle University) have received a grant from the RSSB, with funding from the UK Department for Transport, to develop an Active Radial Suspension System (ARSS) which can be retrofitted to an existing bogie.
The ARSS uses electro-hydraulic actuators originally developed and manufactured by Liebherr for aerospace applications to actively steer wheels on rail vehicle bogies, thus reducing wheel and track wear. The reduction of track wear is of particular significance, as track wear is a notable contributor to the Variable Usage Charge (VUC) Train Operators pay to operate trains on the UK rail infrastructure. The ARSS solution is expected to considerably reduce track wear, and the project aims to validate this, and its potential reduction of VUC.
During the project, the consortium will first model the effects of retrofitting the Liebherr ARSS to an existing UK bogie design – the BT-10. Should the modelling demonstrate the expected benefits, the system will be installed on a trial vehicle and tested in the UK.
The project is expected to be completed by late 2019, which if successful could then be made available for commercial use by Liebherr, both in the UK and other world markets.
