In this study, transmissibility coherence is introduced for system identification with recalling the existing techniques based on transmissibility. Unlike previous approaches that require four-point measurement, the proposed methodology in this study only requires two-point measurement. The merit behind this approach is that the transmissibility coherence can be employed to estimate the subtraction of transmissibility between two reference points, by using auto- and cross-spectrum analysis. Verification using experimental data proves the feasibility of the proposed technique. @ Published under licence by IOP Publishing Ltd. | Source Title: | Journal of Physics: Conference Series | URI: | https://scholarbank.nus.edu.sg/handle/10635/179485 | ISSN: | 17426588 | DOI: | 10.1088/1742-6596/842/1/012020 | Rights: | Attribution 4.0 International |
