Szukana fraza: [Abstrakt = "This paper concerns the optimization of the shape of railway exit transition curves \(TCs\). Exit TCs meant TCs being directly behind the circular arc, and directly before the straight track. As transition curves, the authors used the polynomial of 9th degree. In the optimization of the shape of the curves, the model of 2\-axle rail vehicle was used. The research was performed for three circular arc values and four objective functions. The paper presents the results of the optimization \- the types of curvatures of the optimum reverse transition curves and the dynamical courses \- the displacements and the accelerations both lateral and vertical of the vehicle body mass centres"]
