Abstract： One of the most obvious characteristics for the complex structures, such as ships, is that the vibration response is usually induced by multi-excitations, so study on the rules of that is valuable. A measurement technique for measuring vibration response of structures with multi-excitations was developed and applied to study the vibration characteristics of different cylindrical structures. The measurement results shows that effects of the phase difference on the vibration response and coupled relationship of excitations are obvious, and non linear response for some frequencies exist. When the excitations are non-correlated, the measurement results were compared with the predictions by FEM, which showed the validity of the measurement technique.
