Description

The improvement of current collection performance is necessary to increase commercial speed of Shinkansen. Therefore, contact force between a contact strip of a pantograph and contact wire should be constant. However, contact force fluctuates severely at high-speed domain due to vibration of contact wire and lift force. In this study, contact force control technique by using an air actuator and a PID controller would be discussed to reduce the contact force fluctuation. The control devices were built into a low-noise pantograph and some experiments were curried out by using the current collection testing equipment and the large-scale wind tunnel to validate ability of active control.
