本文的主要工作范围是展示辊弯成型的周向变厚度分布的载荷优化钢管的潜力。以板带型材轧制(SPR)法生产的TRS板卷代替普通板材作为初始材料。TRS薄板是通过横向将一个或多个凹槽轧制到薄板卷材中而在连续加工过程中制造的。本文通过有限元模拟和滚压成形实验，研究了TRS薄板对TRS管的二次成形过程。为了用有限元方法模拟TRS管的制造过程，由于初始SPR板材的凹槽处存在较大的局部应变硬化，因此需要对该过程进行综合考虑。在试验性的辊弯成型操作中，成功地制造了焊管。分析了这些管材的几何性能和材料性能。通过爆管试验研究了TRS管内高压成形后的再加工工艺。研究发现，在液压成形过程中，为了实现凹槽区域的变形，需要额外的退火工艺。
The main scope of the presented work is to demonstrate the potential of load optimized tubes with a varying thickness distribution in circumferential direction produced by roll forming. As initial material a so called Tailor Rolled Strip (TRS) sheet metal coil produced by Strip Profile Rolling (SPR) method was used instead of plain sheet. The TRS sheet metal is manufactured in a continuously working process by rolling one or more groves in transverse direction into the sheet metal coil. In this paper, the secondary forming of the TRS sheet metal to TRS tubes is investigated by means of FE‐simulations and roll forming experiments. To simulate the manufacturing process of the TRS 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 welded tubes could be manufactured successfully. The geometrical and material properties of these tubes are analyzed. The reprocessing of TRS tubes by hydroforming is investigated by means of tube bursting tests. It has been found that an additional annealing process is necessary to achieve deformations in the grooved area during the hydroforming process.
