In the paper the dynamic responses of a multi support structure to an arbitrary excitation waveform is carried out by use of the multiple point excitation approach.

In this paper, a new online detection system, which is designed to inspect the shock excitation with a known waveform is discussed.

For quickly and accurately calculating no-load voltage waveform of harmonic excitation synchronous generators and common synchronous generators, a new method, named as tooth flux method, is proposed.
