Research of geometry effects on the railway track in the alignment, represented in the form of geometric models, on the indicators of the dynamic interaction of the track and rolling stock

The article describes the approach of smoothing previous interpolation interval. Authors studied the influence of track irregularities in alignments between fixed points, realigned the length of the spline function on the distribution of bend values by calculation, for reduction of indicators of the track and rol-of irregularities on circular curves based on the data obtained by ling stock dynamic interaction. This approach is based on spline measurement on one of the of tracks of the Eastern operating interpolation methods, which were used to construct geometric area by track measuring car, and modelling results as well. The models of the track in alignments. The article provides the defini-article presents a comparative analysis of frame forces to assess tion of ”track irregularities in alignments” and substantiates the the impact of the track irregularities in alignments and grades of relevance of the study. The article focuses on the question of the different lengths, which performed using the software package smoothness and the continuity of the geometric model of rail-”Universal mechanism”; the analysis of the calculation was carried way track in alignments and proposes a condition, which allows and it provided the results of research of the dependence of values obtaining the dependence of the position of a point belonging of the frame forces on the loading efficiency of the car in motion to the interpolation interval and the position of the points of the on the length of track with the track irregularities in alignment which were modeled directly according to the measurement of track measuring car and with models of the track irregularities in alignments, developed with different lengths of the spline function. The article outlines the area of practical application of the developed railway track model in alignments and considered the possibility of using the geometrical model of the track in a horizontal plane for problem of maintenance and repair, in particular when setting the track between two fixed points and plotting the step of realigning of three - or four-point system for track lining.
