Abstract

Functional elements which are pressed in sheet metal by forming present a prom-ising technical and economical alternative beside welded studs. Comparable to welded studs, press-bolts enable the opportunity to join parts and components in sheet metal constructions. Beyond that press-bolts offer multiple advantages due to the insertion by cold forming. One of them is that press-bolts provided defined property classes whereby offers the possibility for tightening and preloading. Thermal influence oc-curring in in the metal microstructure do not need to be considered and it is also pos-sible to join coated parts. However, the insertion of these bolt elements applies a struc-tural notch into the support structure. In respect to cyclic loaded constructions, such as railway vehicles, there is no knowledge about the fatigue resistance yet. Concepts of proof or design regulations, as they are commonly used for welded structures, are not available for such metal sections.
