Abstract

Railway transport has been developed for a variety of requirements with a diversity of studies and technologies in recent years. In particular, the intercity railway transport that can be operated at speed of more than 350 km/h is the goal for the railway industry. Due to vibration and drag forces at high speed, contact force variation occurs between pantograph and catenary. This variation also causes instability in the pantograph and catenary interaction. This research deals with the development of a hardware-in-the-loop (HIL) test rig, which allows the reproduction of the dynamical interaction between the catenary and the pantograph in high-speed railways. The design and realization of a test bench that allows the verification of control strategies, of the electrical drive configurations for active control, and of contact force estimation procedures on a real pantograph under conditions that are similar to those encountered on the track. The scope of this research is the development and fabrication of an actual size pantograph unit complete with contact plates, springs and dampers for dynamic behaviours of the pantograph. The catenary is modelled using computer software and represented by electrical actuator. The experiment loop consists of pantograph unit (hardware) and catenary model (software) through sensors and actuators. The outcome of this research is the HIL test rig for pantograph. The HIL test rig makes it possible to verify the control strategies, the electrical drive configurations for active control, and the contact force estimation procedures on a real pantograph under conditions that are similar to those encountered on the real line. Some examples of test bench applications for pantograph active control and contact force estimation are also presented.
