Abstract

The TTX(Tilting Train eXpress) is designed to achieve high driving speed up to 200 km/h and to run on conventional curved rails without speed reduction. In order to maintain power collection between catenary and pantograph collector while train body is tilted, the TTX pantograph must have tilting structure (or Sledge). The power quality is determined by the tilting structure. Static and dynamic characteristics of tilting structure, therefore, are important to evaluate the pantograph performance. The current prototype of the tilting structure is overweight model and its structural characteristics have not been investigated. In this study, the finite element model of TTX tilting structure is established and static analysis is performed. Finally, using this result, a light weight model is proposed.
