Analytical Study on the Influence of Friction on Unstable Oscillation of Pantograph
The sliding of contact strips generates a frictional force acting on traveling pantographs in the horizontal direction. A large coefficient of friction can lead to unstable oscillation of the pantograph. To analyze this oscillation, a 2-degree-of-freedom (2-dof) pantograph model considering frictional force has been proposed. However, this model does not study the stability of the contact strip attached to a pantograph. Therefore, this study proposes a 2-dof contact strip model considering vertical and pitching movements. In addition, excitation tests of an actual contact strip for a Shinkansen train were carried out to identify its dynamic characteristics. The authors then applied a complex eigenvalue analysis to the contact strip model to analyze its stability.
