Удосконалення несучої конструкції кузова напіввагона з метою забезпечення його міцності при маневрових співударяннях

Abstract

UA: У статті наведено результати досліджень міцності несучої конструкції кузова напіввагона в умовах маневрових співударянь. Виявлено зони кузова напіввагона, які зазнають найбільшої концентрації напружень в умовах співударяння. З метою забезпечення міцності кузова напіввагона запропоновано заходи щодо удосконалення його несучої конструкції.

EN: The article presents the results of investigations of the strength of the supporting structure of the body open-top wagon at shunting impacts taking into account the different speeds. Research literature on the safety of wagon fleet during the manoeuvres showed that the speed of collision of the wagons in operation exceed the standard. This causes increased force loading bearing structures gondola body and damaging them. Almost half of all injuries in new wagons occurs when the dissolution from the hills. The greatest percentage of damages falls on the supporting structures of wagon bodies. With the aim of ensuring the strength of bodies of wagons during shunting impacts to meet the increasing speeds of the improved load-bearing structures, by putting on the most loaded areas of the frame reinforcing plates. The thickness of the lining is selected proceeding from the condition of ensuring the strength. Calculation of the strength of the body of a wagon carried out using the finite element method. The results of the calculation of the strength of the body of the wagon with respect to the proposed activities, allowed us to conclude about the feasibility of the technical solutions. In addition, proposed measures for improvement of the supporting structure body of a open-top wagon allow you to maintain the technical condition at the existing repair facilities.
