多个振动源激励是船舶等复杂结构振动响应的显著特点，相应的规律研究具有重要意义。发展了多源激励条件下结构振动响应的试验测量方法，并应用于不同圆柱壳体结构振动特性测量试验。测量结果表明：相位对结构的振动响应和激励源间的耦合关系影响较大，局部频率下结构的振动响应存在较大的非线性。激励源不相关时，振动响应测量结果与有限元预测结果吻合较好，初步验证了测量方法的正确性。

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.
