Abstract
Apar The dynamic characteristics of the current collection system are evaluated during a test run. Signals from accelerometers attached to the pantograph assembly are acquired through a measurement system and analyzed. It is found that the train speed significantly influences the magnitude and frequency characteristics of the pantograph motion. The major frequency components of interest are found to be frequency components originating from the motion of the train along the catenary as well as the several resonance frequencies of the structural vibration of the pantograph. The contact force is also calculated by assuming the pantograph panhead as a rigid structure.
