A hybrid SEA modeling scheme has been developed and applied to obtain an accurate SEA model for a passenger car. In this study, using the SEA model as a reference, uniqueness of the SEA model will be discussed. The SEA model uniqueness will be measured in terms of how accurately dominant power flows are described in comparison with the reference SEA model. An innovative scheme to quantify the differences of the dominant power flow between the test SEA model and the reference SEA model will be developed. Using the scheme, it will be shown that the test SEA model approaches to the reference SEA model as the energy ratios are being matched. Here, the energy ratios, between input power subsystem and a subsystem responding to an excitation given to the input power subsystem, are measured. They have been used to develop the reference SEA model. Therefore, for given freedom in a hybrid process to combine an analytical model and a corresponding experimental model to match the energy ratios by adjusting the coupling loss factors, it has been shown to reach a unique solution.
