- Investigation of control effects on the acoustic behaviour of a force-feedback-actuator – as part of a ZIM project (funded by the BMWi), the Research Group is working with a medium-sized industry partner to investigate the effect of various types of control used in managing the sound radiation of a force-feedback-actuator. Here, the main focus of research is on the inverter-fed, synchronous motor of the actuator which depicts a significant source of vibration excitation.
- Acoustic behaviour of bearings/special gears – the forces and deformations in elliptically deformed balls are being investigated, like those used in strain-wave gear. Therefore, a numerical simulation model is being developed and synchronized with measurement data. The goal is to specify the ball forces, the shaft’s restoring force, and accelerations that act on the surface of the bearing (for diagnostic purposes) with respect to construction parameters.
