Optimizing Running Dynamics of the DLR Next Generation Train with Mechatronic Track Guidance

Abstract

In the research project “Next Generation Train”, DLR is developing a concept for a double-decker high-speed train. The concept includes two-axle intermediate wagons, which have single-axle running gears with independently rotating wheels (IRW) and mechatronic trackguidance. This enables centering in the track and active radial steering for IRW pairs during curve passing. Thus, wheel wear and noise generation can be considerably reduced. SIMPACK multi-body simulations are used to verify and optimise the dynamic behaviour. The main tasks of the simulation are optimisation of the mechatronic track guidance and optimisation of the suspension parameters for high ride comfort.
