DYNAMIC RESPONSE ANALYSIS OF PANTOGRAPH - CATENARY SYSTEM

초록

One of the main problems in high-speed trains is the contact force variations. The contact force variation can cause contact losses, arcing and sparking. If the spark happens between the pantograph and the overhead catenary system, the EMI(electro magnetic interface) and noises may occur. All of these problems can potentially damage the relatively fragile carbons of pantograph. After all, the quality of current collection is deteriorated. This problems are related to the dynamic interaction between the pantograph and the catenary system. As the train speed increases, the oscillations becomes larger and the loss of contact becomes larger. This paper deals with the dynamic response analysis between pantograph and overhead catenary system under various operational conditions.
