Railway applications - Current collection systems - Validation of simulation of the dynamic interaction between pantograph and overhead contact line

Simulation techniques are used to assess the dynamic interaction between overhead contact lines and pantographs, as part of the prediction of current collection quality. This document specifies functional requirements for the validation of such simulation methods to ensure confidence in, and mutual acceptance of the results of the simulations.
This document deals with:
- input and output parameters of the simulation;
- comparison with line test measurements, and the characteristics of those line tests;
- validation of pantograph models;
- comparison between different simulation methods;
- limits of application of validated methods to assessments of pantographs and overhead contact lines.
This document applies to the current collection from an overhead contact line by pantographs mounted on railway vehicles. It does not apply to trolley bus systems.

Železniške naprave - Sistemi tokovnega odjema - Veljavnost simuliranja medsebojnih dinamičnih vplivov med tokovnim odjemnikom in kontaktnim vodnikom - Dopolnilo A1

Simulacijske tehnike se uporabljajo za oceno dinamične interakcije med nadzemnimi kontaktnimi vodniki in tokovnim odjemnikom kot del napovedi kakovosti tokovnega odjema. Ta dokument določa funkcionalne zahteve za potrjevanje takšnih simulacijskih metod, ki zagotavljajo zanesljivost in obojestransko sprejemanje rezultatov simulacij.
Ta dokument obravnava:
– vhodne in izhodne parametre simulacije;
– primerjavo z meritvami preskusov vodnikov in značilnosti teh preskusov vodnikov;
– potrjevanje modelov tokovnih odjemnikov;
– primerjavo med različnimi simulacijskimi metodami;
– meje uporabe potrjenih metod za ocene tokovnih odjemnikov in nadzemnih kontaktnih vodnikov.
Ta dokument se uporablja za tokovne odjemnike, nameščene na železniških vozilih, ki odjemajo tok iz nadzemnega kontaktnega vodnika. Ne uporablja se za sisteme trolejbusov.
