The paper is focused on the discussion of a new double-axle flexible bogie for a high-speed train. The main feature of the flexible bogie is that is consists of two sub-bogies connect with diagonal links. Moreover an elastic connection between a carriage and both wheelsets is introduced. These features, helping to increase the bogie flexibility by passing tracks with a low radius of curvature, are studied in this paper numerically. The results demonstrate a great potential of the bogie and ability to travel with no significant oscillations at speed of 432km/h. Numerical optimization of the bogie’s parameters is performed in order to maximize the ride comfort.
