Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]
, 2016 The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment [PDF]
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.

Research of geometric parameters of symmetric railroad switches [PDF]
MATEC Web of ConferencesTurnouts are a barrier in the track for setting the permissible speeds of trains movements on the main tracks, as they have special structural devices for branching traffic from the main track to the side one.

The interaction between railway vehicle dynamics and track lateral alignment [PDF]
, 2016 Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...

Revisiting the reasons for contact fatigue defects in rails
MATEC Web of Conferences, 2017 As it is known rail is one of the most significant elements of the whole railway construction. Operation under alternating loads from wheels of the rolling stock and different ambient temperatures lead to appearance and development of rail defects and ...

An investigation of sleeper voids using a flexible track model integrated with railway multi-body dynamics [PDF]
, 2009 This article describes a flexible track system model (FTSM) that represents the track structure for a typical ballasted track, taking into account the flexibility of the rails, the sleeper mass and the resilience of the pad/fastening elements, as well as

A longer service life of intermediate elastic fastenings KPP-5 due to application of pads PRP-3.2
MATEC Web of Conferences, 2018 Since 2003 Ukrainian railways have used KPP-5 intermediate elastic fastenings. These fastenings unlike their predecessors (for example, terminal-bolted fastenings (KB) widely used on railways), first of all, have fewer elements.

MATEC Web of Conferences, 2017 At present, the most common track model is the one in which rails are presented as bars of infinite length rested on continuous elastic foundation. However, some specialists consider the model to be rather ideal for railways in terms of track and the ...
