A Study on the Measurement of Contact Force of Pantograph of Korean High Speed Train
초록
The pantograph for Korean High Speed Train was developed by home-grown technology. In this study, a system to measure the contact force of pantograph is developed and installed on the prototype high speed train, Contact force prevents the pantograph from separating from the catenary. However, excessive contact force causes rapid erosion of catenary. The contact force can be divided into lift force and spring force. Contact force measurement is conducted while the train runs on the test track. The lift force is measured by the load cell on the roof separately and combined with the spring force of pan-head to form the contact force. Measured results show that the contact force of the pantograph of Korean High Speed Train is below the upper limit regulated by the high speed train standards. The contact force measuring system provides data to evaluate safety of the catenary system.
