Study of Vibration Influence Mechanism with Load for Marine Synchronous Generator

In this paper, influences of different loads on the electromagnetic vibration of Marine generators during stable operation are studied. The electromagnetic vibration response model is established by theoretical analysis of the variation rule of the internal synthetic magnetic field of the generator under the load of inductive or resistance. Maxwell tensor method is applied to deduce electromagnetic waves under different synthetic magnetic fields, and modal superposition method is used to calculate the vibration response of generator stator. Finally, it is verified by ANSYS Electronics simulation and experiment, and the experimental results are consistent with the theoretical analysis results.
