1. Introduction
Full-scale measurements can significantly contribute to understanding the dynamic behaviour of a structure. The nature of the structure determines which types of measurements are best suited for analysing its behaviour. In addition, the environment (e.g., location, usage) of the structure may also favour or exclude certain types of measurements. It is therefore necessary for a monitoring system to be designed specifically for each type of structure. In the case of railway catenary sections, it is important to assess their behaviour as trains pass through the sections. In addition, the system that is assessed while the trains pass through the sections is a coupled dynamic system consisting of two dynamic systems: the moving pantograph and the spatially stationary catenary section. Uninterrupted contact between the pantograph and the catenary system is essential for maintaining electrical power to the train [1]. The complexity of this interaction and the dynamic responses increase with increasing train speed [2], and speeds above the design speed make the dynamic response even more critical [3]. In general, railway catenary systems are considered lightly damped [1,4,5], so oscillations are present in a substantial time around the actual contact point on a catenary system [1]. Thus, the quality of contact is directly dependent on a desired structural behaviour and to the amount of wear. This is of even greater importance on lines where multiple pantographs is used.
