Leaf springs are widely used for the suspension system in trains and commercial vehicles to absorb vibrations and shocks. This paper deals with the methodology of analysis of the leaf springs of the freight railway wagons by using software package Ansys 14.5. The methodology is applied in a concrete example of leaf spring for axle load of 225 kN. The procedure of forming the CAD model of the leaf spring using AutoCad and Autodesk Inventor is exposed, as well as the development of numerical model in Ansys software package. The results of the static analysis of given leaf spring are presented and commented.
