Kurzbeschreibung (Abstract)

The main scope of the presented work is to demonstrate the potential of load optimized tubes with a varying thickness distribution in longitudinal direction. As initial material a so called Strip Profiled Rolling (SPR) sheet metal coil was used. The SPR sheet metal is manufactured in a continuously working process by rolling one or more groves in longitudinal direction into the sheet metal coil. In this paper, the secondary forming of the SPR sheet metal to SPR tubes is investigated by FE-simulations and roll forming experiments. To simulate the manufacturing process of the SPR-tube by FEM, an integrated consideration of the process is necessary because of the large local strain hardening in the groves of the initial SPR sheet metal. In experimental roll forming operations successfully welded tubes could be manufactured and analyzed for resulting properties. Tube bursting tests were conducted to prove the applicability of SPR-tubes for tube hydro forming operations. To achieve deformations of the grooved area during the hydro forming process an additional annealing process is necessary.
