| Summary: | The current collection system consists of a
pantograph placed on the roof top of a trains’ vehicle and
overhead contact wire supported by evenly spaced vertical
holders which supply the current to the pantograph from
the electric power grid. Most of the pantographs produce
averagely good performances at low and medium speeds,
approximately less than 250 km/h. However, at higher
speeds, the response of the pantographs is distorted. Thus
the stability of the current collection is in peril. In addition,
due to vertical vibration of the car body during high speed,
contact force variation occurs between the pantograph and
overhead wire. Therefore, it is necessary to maintain the
contact between pantograph and overhead wire. In this
study, the multi-body dynamics analysis is used to model the
flexible body of overhead wire. An excitation experiment is
performed in order to determine the parameters of
pantograph. With consideration of vertical body vibration,
an active pantograph control is developed to eliminate the
effect of vibration to contact force, reduce the maximum
peaks and avoid contact loss. |
