Reliable straightening-tamping machines

Keywords: railway track, integrated indicators of reliability, straightening - tamping  machine, track machines

Abstract

In this article the developed and implemented a model that allows us to estimate an integrated performance reliability of liner- tamping - straightening machines at specific sites of railway track based on actual field observations during the operation of the straightening - tamping - straightening machines VPR- 02 and VPRS - 02 per between 2001 and 2012 at the site of the West - Siberian infrastructure Directorate - the structural unit of the Central Directorate of infrastructure - branch of JSC " Russian Railways " and annual reporting documentation management operation and maintenance of machinery for travel . Partially processed information is obtained based on the results of field observations of the process of machine operation VPRS -02 , which is located at the site of the Siberian State University of Railways in 2007 as part of laboratory work in various academic disciplines : "Apparatus and bases of calculation of track machines ", " travel machine ", " drives track machines "," Operation Track Machine " conducted on the machine.
