Possible modelling methods are discrete mass-spring-damper-models, multi-body systems, finite-element-models or thetransfer function of the pantograph.The characteristics of control and the dynamic characteristics of active pantographs shall be available forthe modelling method.6.2 Minimum dataThe 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 line7.1 General requirementsThe model of the overhead contact line shall describe the dynamic characteristics in the frequency rangeof interest.T
