Szukana fraza: [Abstrakt = "The object of paper is problem of influence of local simulated une venness on rail static work in vertical plane. An analysis of planned unevenness in jointless track \(simulating an unevenness arising during its operating\) is inserted. The terrain researches in real railway track with planned unevenness are carried out. These researches allow to state, that the author’s method to generated local unevenness with initial parameters \(length and sag\) is useful in real track. A special accent is paid on significant change of conditions work of operated rail due to arising in it ’s the unevenness. Growing unevenness causes a various contact between sleeper and ballast layer. The track stiffness causes in unloaded state \(without loads from vehicle\), that sleepers in various state support on ballast. In most unfavourable case can appear a contact loss between sleeper and ballast – e.g. effect “hanging sleeper\/sleepers”. Changing the way of track support can be described only in loaded track after imposing a wheel load \(e.g. from successive locomotive axles\). In the paper a special accent is laid on visualization the influence of selected factors on work of CWR track rail, giving in many places in the paper the proper figures and graphs carried out from making site researches and calculations."]
