| Abstract [eng] |
The paper deals with the problem of evenness of train running on dual track curves in the route “Kaunas–Poland Border of new built railway line ”Rail Baltica“. Authors examined the stability and smoothness of rail vehicle running on railway track curves of dual gauge. Traffic safety conditions of passenger coach is analysed and assessed according to four parameters: maximum permissible speed, risk of rail vehicle derailment, uncompensated transversal acceleration and lateral displacements of running gear. The train running smoothness was analyzed considering the main parameters as the radius of horizontal curves, the superelevation of outer rail and the impact of unsuspended transversal acceleration. The movement of four-axle coach on track with given vertical and track transversal irregularities was simulated by using software package „Universal Mechanism”. Gained research results are compared with the maximum permitted speed on „Rail Baltica“ track curves. Finally, basic conclusion and recommendations for designing of dual track curves in are given. |
