A classification of side frames for three-piece bogies was proposed. For side frames with elastic primary suspension finite element models considering this interaction, as well as the elastic interaction with the secondary suspension, were developed and verified through testing. An evolution series of side frames to optimize the strength and mass of the construction was developed analyzing stress concentration zones and methods to eliminate them.
