Gauging analysis

Project tasks

• Gauging analysis of railway vehicles according to EN 15273
• Gauging analysis of vehicles according to BOStrab
• Calculation with special simulation programs cMotion or DIMA
• Simulation of complex articulated vehicles, e.g. light rail vehicles
• Consideration of national requirements (e.g. EBO resp. BOStrab in Germany or AB-EBV in Switzerland, etc.)
• Consideration of requirements from network accesses (e.g. SBB I-20030 in Switzerland)
• Gauging analysis of narrow-gauge vehicles according to AB-EBV
• Analysis of special vehicles (e.g. suspended railways)

Our Approach

At first a verification concept is developed based on the customer’s specifications as well as requirements from infrastructure and standards. This can include the following, depending on the specific task:

• Simple delta analysis (e.g. design adaptions or interoperability concerns)
• Regular construction gauge calculation with static or kinematic methods
• Calculation of gauging demand by means of accumulation of critical positions of the bogies in the track gauge, design tolerances, plays, etc. with distinction of random and non-random contributions
• Simulations by means of the tool cMotion to model arbitrary vehicle configurations and track routing
• Application of dynamic methods supported by simulations (e.g. swinging characteristics for suspended railways)
• Development assisting analysis with continuous assessment and consulting
• Validation via simulation or measurement (e.g. multi-body simulation or field test runs with attached blocks)
• Compilation of input data, procedure and results to a report, ready to be submitted to Technical Authorities

Customer benefit

Due to the wide range of available methods and the long-standing expertise of the PROSE-experts arbitrary vehicles and requirements can be investigated. Potential problems will be anticipated and prevented. Manifested problems can be furthermore solved by experts of other disciplines. Additionally, a special focus on efficiency lies in our DNA as a service provider. Combined with a tailor-made concept for the customer and project this overall ensures that technical risks in development, homologation and operation as well as commercial overall efforts will be minimized.
