Study on the Elastic Elements that Equip the Bogies of Freight Railway Cars

摘要

The theoretical study has focused on the computation conducted for the helical springs of the suspension on the Y25Lsdi bogie, which equip freight railway cars. The axial compression load type was chosen since the helical springs with wire diameters of Ø31mm and Ø24,4mm respectively are connected in parralel with the bogie suspension. The studied springs were supported on their transverse section, on the end of the bogie cradle, and the compression forces were applied to the opposite end in accordance with the situations encountered in use.
