(Main)Railway applications - Current collection systems - Validation of simulation of the dynamic interaction between pantograph and overhead contact line
Railway applications - Current collection systems - Validation of simulation of the dynamic interaction between pantograph and overhead contact line
This European Standard specifies functional requirements for the validation of simulation methods to ensure mutual acceptance of
– input and output parameters;
– a standardized subset of test results for evaluation of simulation methods;
– comparison with measurements;
– comparison between simulation methods.
This standard applies to the current collection from an overhead contact line by pantographs mounted on railway vehicles. It does not apply to trolley bus systems.
