Research and Design of Construction of a Bearing Plate of a Counter Rail Attachment Fitting

While implementing the perspective programs of “RZhD”, JSC (high-speed movement, heavy-load movement, resource saving etc.) connected with efficiency increase of railway transport, it is necessary to provide the safe functioning and reliability of all elements of the high layer of the track.The given article considers the research of the stress-deformed condition in a bearing plate of a counter rail attachment fitting of turnouts. The bearing plate gets out of order as a result of a multi-cycle endurance destruction. Based on developed methods of the experimental research, a scheme discrete model of a counter rail attachment fitting of the turnout was created. The article studies the influence of constructive parameters of a spacing lug and latches on the bearing plate load. The results of the experimental research are used for development and projecting of a new construction of a bearing plate for a counter rail attachment fitting, the patent of useful model 152367.The authors conducted the comparative research of the stress-deformed condition of bearing plates with the model of a high way construction consisting of three sleepers with a base rail, counter rail and a base plate with two variants of plates: standard and new. An experimental layout of bearing plates was designed which is now being tested and exploited in the Southern Ural Railway.
