Depending on the phenomena to be studied, the frequency range of interest shall be defined in advance and shall be consistent with the pantograph model, overhead contact line model and simulation method and with the measurement system. The simulation method shall be assessed by the use of comparisons between the results of the simulation and line tests or by comparison with other validated simulation methods. A validation of the method shall be done in accordance with clause 10. In order to be used with confidence the simulation method shall be evaluated. The evaluation for a simulation method shall be done with the two steps which are shown in Figure 1. – 7 – EN 50318:2002 Start validation Benchmark with reference model (see clause 11) Unchecked simulation method line test results conditions Xn Step 1 validated simulation method validation acc. to sublause 10.1 for conditions X n step 2 validated simulation method for condition X n usable in ranges acc. to subclause 10.2 further conditions End validation 2 1 1 1 2 simulation input for conditions X n acc. to clause 6,7,8 n n y n y validation step 1 validation step 2 y Figure 1 – Steps of evaluation subclause EN 50318:2002 – 8 – 6 Modelling of the pantograph 6.1 General requirements A pantograph model shall describe the dynamic characteristics of a pantograph in the frequency range of interest.

The characteristics of control and the dynamic characteristics of active pantographs shall be available for the modelling method. 6.2 Minimum data The following parameters of the pantograph shall be available for simulation: – kinematics; – mass distribution; – degree of freedom of joints; – damping characteristics; – spring characteristics; – friction values; – stiffness; – bump stops; – location of application of the static force; – location of application of the aerodynamic forces. NOTE Aerodynamic forces usually depend on the orientation, operation height and position of the pantograph and the type of train. These parameters shall take into account other dependencies (operation height, stagger, non-linearities, frequency), if required. 7 Modelling of the overhead contact line 7.1 General requirements The model of the overhead contact line shall describe the dynamic characteristics in the frequency range of interest. The overhead contact line may be modelled with two- or three-dimensional geometry, depending on the phenomena to be investigated.

The length of the overhead contact line model shall be at least three times the spacing between the first and last pantograph, with a minimum of 10 spans; – length of each span; – position of droppers; – contact wire height (sag, dropper length, wire gradients); – encumbrance at the supports; – geometry and mass distribution of steady arms; – stagger; – number and characteristics of wires (contact wire, catenary wire, auxiliary wire, stitch wire, droppers, …); – mass per unit length of the wires or density and cross-section; – mechanical tension of wires. Where the tension depends on temperature, this relationship shall be specified; – mass of links between wires and droppers (clamps); – the mechanical characteristics of the supports and structures; – the stiffness characteristic of droppers. 8 Parameters of simulation The parameters of the pantograph and overhead contact line shall be given according to clauses 6 and 7. In addition, the following parameters shall be defined if applicable: – train speed; – analysis section; – number of and distances between pantographs; – static force of each pantograph; – aerodynamic forces of each pantograph; – operation height of the pantograph; – wire temperatures; – damping of the overhead contact line; – frequency range of interest. EN 50318:2002 – 10 – 9 Output The simulation shall calculate the variation of the contact forces, the wire movements and the pantograph movements when the pantograph passes along the overhead contact line model. The output parameters shall be filtered to exclude frequencies outside the frequency range of interest. The outputs from the simulation shall be analysed over the analysis section. The following subclauses specify the outputs for a single pantograph. If the train has more than one pantograph, then the output shall be available for each pantograph. 9.1 Contact force Required outputs: – mean value of the contact force FM; – standard deviation of the contact force �; – statistical maximum and minimum of contact force; – actual maximum and minimum of contact force; – statistical distribution (histogram) of contact force.
