摘要：

Numerical methods of calculating the electromagnetic forces and of simulating the oscillation behavior of the stator end winding are introduced. The end winding oscillations of different turbo generators under forced vibrations are computed in a combined simulation. Also eigenfrequencies and eigenmodes are determined. The obtained results are surveyed by measurements. Numerical simulation of oscillation behavior is found a useful tool in end winding design although model parameter identification still offers improvement potential.
