고속 틸팅열차 판토그라프 양력조절장치의 수치해석

초록

The development of a tilting train with construction of electric line on the conventional railway is required for speed-up on the conventional railway with many curving sections. The study and development of the pantograph tilting mechanism in order to keep a good contact behavior between a pantograph and a contact wire by tilting a pantograph on the opposite direction of the vehicle tilting direction. In the last study, we analyzed the aerodynamic characteristic of a developing pantograph on the tilting train and obtained the contact force with catenary by aerodynamic lift force by the aerodynamic analysis. In this study, we perform the numerical analysis for design the airfoil controlling lift force on a pantograph. From the aerodynamic simulation and parameter study for the airfoil to control the lift force, we analyze the characteristic of airfoil for the various shape and will suggest the optimal shape of it corresponding to a developing tilting pantograph. The Fluent software is used for the calculation of flow profile in this study.
