N2 - The complex vibration source identification of structure in the vibration analysis and control is an important aspect that people pay more attention. First, the complex vibration system of structure is divided to several related subsystem each other in the paper. The model of subsystem-input/single-output system is established. The correlations between inputs and the model after average process in multi subsystem-input system are developed. The value changes of correlated input matrix and the affecting to the output in various relevant condition of subsysteminputs are analyzed. According to coherence analysis, the method to estimate the contribution of inputs to the output is obtained. And the accuracies of method are verified by simulation. Finally, the vibration data are given by an automobile test. After the data analysis, the usefulness of new method provided in the paper is verified.
