Abstract: The dynamical behaviour of passenger high-speed bogies during passage through the turnout is one of the most important factors in the safety of the vehicle. By increasing the speed of wagon when passing through the turnout, safety parameter and wheelset forces should be considered. The purpose of this paper is to study and analyse the dynamics parameters of passenger wagon and safety of a bogie, such as the derailment and the forces of the wheelset when passing through the turnout with different turnout rail profiles, because the type of turnout rail profile and geometry of turnout affect dynamic performance of bogie. The simulation of a wagon in a multi-body dynamic (MBS) UM software has been used on turnouts with different rail profiles and radius of turnout. The geometric features of the turnout, such as its radius and turnout rail profile, have greatly influenced the dynamics of the wagon.

Keywords: turnout; derailment coefficient; high speed bogie; dynamic simulation; lateral dynamic forces; turnout geometrical specification; ride comfort.
