ИЗСЛЕДВАНЕ НА ВЪЗМОЖНОСТТА ЗА РЕМОНТ НА СЧУПЕНИ ЛИСТОВИ РЕСОРИ НА ТОВАРНИ ВАГОНИ ЧРЕЗ ЗАВАРЯВАНЕ

Драган Петрович, Милан Бижич,

- Целта на тази статия е да проучи възможността за ремонт на счупени листови ресори (ЛР) на железопътни вагони чрез заваряване. Счупванията на ЛР са много чести, особено за товарни вагони, използвани при екстремни условия на работа. Един от начините за решаване на този проблем е ремонт чрез заваряване на счупените листове. В този случай се повдига въпросът за поведението и характеристиките на ремонтираните ЛР. Подходът в тази статия е базиран на сравнително експериментално изпитване на ремонтирани ЛР и нови ЛР. Целта е да се определи ефекта на заварените листа върху поведението и характеристиките на ремонтираните ЛР. Получените резултати показват, че заваряването не влияе значително върху поведението и характеристиките на ремонтираните ЛР. По време на изпитванията на умора не е регистрирана повреда в зоната на заварката. Резултатите показват, че жизнения цикъл на ремонтираните ЛР е малко по-нисък по отношение на новите ЛР. Крайното заключение е, че заваряването може да бъде възможно решение за ремонт на счупени ЛР.
