Pantograph/overhead line test laboratory
Pantograph/overhead line test laboratory
Our test laboratory utilises state-of-the-art, proven measuring equipment when conducting standard measurements and carrying out individual, customised measurement services: – Stationary in laboratory – Static and dynamic tests (e.g. for accompanying measurements during railway operation field testing) Accredited test procedures: Our test laboratory in Munich is accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS) in accordance with EN 50327 for – Contact force measurements – Uplift measurements – Pantograph arcing measurements – See the appendix for the accreditation certificate. Our tests and test quantities: Analysis up to 350 km/h on pantograph test stand DB Systemtechnik has a state-of-the-art pantograph test stand. This test stand can be used to reproduce and analyse the mechanical properties of a pantograph under real-world conditions at speeds of up to 350 km/h. Validation of pantograph measurement systems – Testing of contact force measurement systems connected to the pantograph – Basis for approving the measurement system for acceptance runs – Basis for approving overhead line inspection systems Generation of pantograph simulation models – Coordination of model parameters based on dynamic measurements with the pantograph in the test stand Analysis of the effect of modifications to the pantograph – Facilitation of a pre-selection of optimised solutions without the need for test runs Development of new measurement systems and pantograph or pantograph control systems prior to conducting measurement runs Our simulations: Computer simulations i.a.w. EN 50318 for contact and uplift forces: DB Systemtechnik uses a powerful simulation application to analyse the interaction of the pantograph and overhead line as part of development activities or approval procedures. By leveraging the simulation results obtained, processes can be implemented to optimise individual components or conduct weak-point analyses quickly and without the need for elaborate test runs. The PrOSA simulation software used is validated in accordance with EN 50318, whereby the results of the simulation exercise are compared to actual measurements taken. Thanks to the high level of flexibility afforded by the program, the different parameters of the pantograph and overhead line as well as their physical properties can be configured exactly as required. Overhead line: – Development of new overhead line constructions – Further development of existing chains Pantograph – Development and optimisation of pantographs – Approval of new rail vehicles (combination of test runs and simulation exercises) – Development of algorithms to control active pantographs in real time Overhead line/pantograph interaction – Investigation and analysis of dynamic correlations – Investigation and determination of system-relevant borderline cases (maximum speed, maximum number of pantographs, influence of pantograph spacing) Our special-purpose measuring vehicles: – HSR measurement train (ICE-S) – NeiTech measurement train (VT 612) – Sound measuring train – Radio measurement car – Additional measuring vehicles, train drivers and testing supervisors Our stationary test stands: We have a pantograph test stand. DB Systemtechnik is QMS certified to the ISO 9001 standard.
