Abstract

This paper is focused on the discussion of a new double-axle flexible bogie for high-speed trains. The main feature of the flexible bogie is that it consists of two sub-bogies connected with diagonal links. Moreover, an elastic connection between the carriage and both wheelsets is introduced. These features, which help to increase the flexibility of the bogie while passing tracks with a low radius of curvature, are numerically studied in this paper. The results demonstrate the huge potential of the bogie and its ability to travel without significant oscillations at a speed of 432 km/h. Numerical optimization of the bogie's parameters is performed in order to maximize ride comfort.
