Damage evolution in the production of drive shafts by radial swaging and spline drawing (T01#)

• Subject Area: Primary Shaping and Reshaping Technology, Additive Manufacturing
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 278868966

The aim of the transfer project is the production of highly stressed drive shafts for electric drive concepts with reduced damage and thus increased performance by incremental forming processes. The processes used for this purpose are radial swaging for the production of hollow shafts with undercuts and variable wall thicknesses and spline drawing for the production of longitudinal splines. To this end, the basic knowledge developed in CRC/Transregio 188 on the relationship between load path, damage and performance is to be transferred to a complex, industry-oriented process sequence.
