Kurzbeschreibung (Abstract)

This contribution presents a manufacturing method for producing hollow shafts with integrated sensors. An incremental forming process is used to join a deformation sensing element in a tubular part during forming. A mechanical pre-tension is created to ensure a high linearity. The sensor signals are utilized during manufacturing to monitor and control the processes. Control and monitoring strategies are derived in order to achieve a constant quality of the sensory structures. In order to design the joining process a numerical model is used. The resulting pre-tension force could be predicted numerically with a deviation of 30 for aluminum and 6 for the steel tubes. A 32 x 4 mm hollow shaft is produced and characterized with ±1.2 kNm on a torque testing machine. A demonstrator with an integrated miniature measurement amplifier illustrates the high potential of measuring at the inside of rotating or moving parts to exploit inaccessible measurement regions.
