Overhead contact lines (OCLs) are subjected to longitudinal displacement due to factors such as temperature changes and external force. Excessive longitudinal displacement may prevent the tension balancers from performing their proper tension adjustm

Condition monitoring technology has advanced remarkably in recent years in various areas, including railways. Since the overhead catenary system and the pantograph in railway does not have enough redundancy, failures of the overhead catenary system o

In recent years, condition monitoring methods have been widely developed. Any failure of the overhead catenary system or pantographs will raise the long downtime of railway operation. Therefore, condition monitoring methods of pantograph failure is r

The frictional force acts to the travelling pantograph head in horizontal direction due to sliding of the pantograph head and contact wire. Therefore, vertical motion of the pantograph head is generated by link mechanism of the pantograph. If the coe

It is necessary for pantographs of Japanese high-speed trains to satisfy both low noise characteristics and insensitive lift force characteristics toward the variation in wind direction and in the shape of pantograph head due to wear. Taking particul

This paper provides a hybrid simulation (HS) system for pantograph/catenary systems based upon the dynamically substructured system (DSS) method. HS consists of a physical pantograph, an actuator to excite the pantograph head and a real-time simulato

This paper proposes a feedforward controller for active suppression of contact force fluctuation between a pantograph and overhead contact line of a high-speed railway vehicle, assuming the use of a pneumatic actuator with low response speed. The pro
