Vibration Analysis of a Coach with the Wheel-flat Due to Suspension Parameters Changes

This article is focused on the vibration analysis of the coach, which wheel is damaged by the wheel-flat. Analyses are carried out in multibody software and results are evaluated in terms of influencing suspension parameters change on accelerations output signals. The article consists of two parts. The first part is aimed on the problem of damaged wheels origin and its consequence during rail vehicle running on tracks during real operation. There is also included the system of forces and accelerations measurement during rail vehicle running on the given track section. The second part is focused on the assessment of selected measured parameters of a rail vehicle with wheel-flat which are obtained from computer simulations. As evaluation parameters signals accelerations in the selected location during passenger car running on the straight track for various stiffness of coil spring of the primary and secondary suspension were assessed.
