摘要: Operational modal identification method is a procedure that ertracts modal parameters of a structure only from its response, it is always based on an assumption that excitations are white noise. For a ship structure, its excitations are very complex, including sea waves, main engine and propeller excitation and so on. These excitations can be assumed to be a combination of white noise and some harmonic signals. Here, based on characteristics of ambient excitations of a ship structure, special methods for operational modal parameter identification were discussed, and then application of NExT/ERA in a ship structure was introduced. At last, these methods were verified with the general modal parameter identification of a real ship structure.
