Analysis of peculiarities of passenger car body wear

The article considers the issues of analysis of the patterns of operation of the loadbearingelements of the body of carriage. A comparative analysis of the size and nature of theoperation of structural elements of carriages of different types and years of their construction.In recent years, there has been a significant aging of the operational fleet of carriage. Atnowadays, carriages of various models and their modifications with an extended service life, whichis approaching the limit, are in operation on the railway network of Ukraine.The technical, economic and ecological indicators of transport, the degree of reliability andtraffic safety depend on the age of the carriages. At nowadays, the level of development of technicalmeans and technology of repair and restoration of rolling stock is increasing fast.To increase the competitiveness of rail passenger transport, it is necessary to overcome thehigh degree of wear of the carriages fleet of JSC «Ukrzaliznytsia». Because of the lack of domesticand the complete absence of foreign investment in the railways, the tendency to increase physicaldepreciation and obsolescence of fixed assets is progressing. According to the data of the branch of«Passenger Company» JSC «Ukrzaliznytsia» in 2020 the inventory includes is almost 5 thousandcarriages, most of which have served their intended service life. As a result, the current wear of thecarriages fleet is approaching 92 %.Most of the carriages fleet was built in the 70s and 90s of the last century at car plants inGermany and Russia. Due to the constant lack of funding, the fleet of carriages of JSC«Ukrzaliznytsia»was renewed at a slow pace. Every year the carriages fleet wears out and ages. Thisreduces the competitiveness of railways, which negatively effects on quantity of passenger traffic.Naturally, carriages should not only create the necessary level of comfort, but also ensure trafficsafety and high reliability in operation. The results of the study made it possible to consider the issueof further use of carriages, which are most affected by corrosion.
