Szukana fraza: [Abstrakt = "In the paper the chosen imperfections of railway subgrade causing on additional rail deflections in jointless tracks were analyzed. For such imperfections the following problems were selected\: \- contact loss between track and roadbed, \- wheel load on local subgrade unevenness, \- wheel motion in the neig hborhood of rail joint, \- change of support stiffness on rail deflection of CWR track. Also an attention was paid on sources of additional unfavorable deflections are others factors, e.g. a work of jointless track resting on local roadbed unevenness or a character of interaction between wheel and rail. The presented static analysis has shown the meaning of unfavorable influence of selected factors on CWR track work \(e.g. length increase of contact loss between track and subgrade or the arising additional deflections of rail\).In the paper a special attention was paid that such imperfections, apart from obtained additional deflections, cause among other things a disturbance of translational motion of rolling stock due to arising imperfections. In the paper a special accent was laid on visualization the influence of selected factors on work of CWR track rail, giving in many places in the paper the proper photos, figures and diagrams from obtained calculations. In the paper were given the proper publications, in which in the comprehensive way the complete procedures of theoretical analysis of considered problems are shown."]
