Rotor Test Bench
To validate numerical simulations of the rotordynamic model, a test bench was built. Hereby the rotor is driven by a permanent-magnet synchronous motor which is controlled by a Bernecker and Rainer system and the motor torque is transmitted with a spur gear pair. These are chosen to analyze parametric excitation based on varying tooth mesh stiffness. Also a second drive coupled via a tooth belt to the rotor can be attached.
