Project tasks

• Clarification of the intended track layout, speed restrictions and wheel/rail profile conditions 

• Setup of appropriate multi body system (MBS) models of the tracks including the cross-sections of the switch blades as well as three types of existing tram vehicles 

• Conduction of a variation of MBS simulation runs and extraction of loads acting on track components like e.g. rails, switch tongues; setup of related load assumptions 

• Setup of a finite element model (FEM) e.g. of the switch tongues and the surrounding structure 

• Fatigue strength assessment of the track component while applying the loads as gained from the MBS simulations 

• Proposals of design improvements regarding the strength 

• Meter gauge tram application 

• Tracks including deep grooved switches
