Riding quality of a new rail route of the Würzburger Straßenbahn

The Würzburger Straßenbahn GmbH commissioned PROSE to determine the riding quality of a planned rail route in relation to the existing fleet of trams. It had to be verified whether the safety against derailment can be guaranteed and that no damages are caused by too large forces between the vehicle modules.

Based on the planned route, PROSE performed simulation calculations and changed these under given conditions specifically until the riding quality was achieved. Special challenges were the construction of simulation models of older existing vehicles, the determination of detailed vehicle data, the reasonable estimation of missing data and the subsequent plausibility check of the model. Therefore, the PROSE test laboratory had determined essential parameters on the vehicles in advance by measurement. In addition, the routing is a specially challenging task that is close to the limits of physics due to its topology with gradients of up to 90 per mille and arc radii of sometimes only 20 metres. PROSE followed a holistic and structures approach from the individual solution proposal to the measurement of essential properties and the model construction including plausibility checking up to a specific result.

The customer benefits from the timely planning security regarding the technical feasibility of the planned route and can therefore avoid late consequences such as cracks in the vehicles after the completion of the track construction. In addition, the vehicle models developed by PROSE will be available for future investigations, which strongly minimises further initial effort. The vehicle models are documented software-independently. Therefore, the customer is provided with a complete data set of all driving-related values for each vehicle type.

The combination of know-how about tram vehicles and their components, the experience in multi-body simulations, full knowledge of the relevant regulations and the availability of an in-house test laboratory enable PROSE to offer comprehensive solutions.
