内容記述 | A dual correlated random excitation technique is presented for estimating the modal parameters of symmetric structures. In this procedure, a pure random signal is used to drive each of two identical excitation systems located at symmetric positions of the structure in order to reduce the number of degrees of freedom in a given measurement by separating symmetric and anti-symmetric vibration modes. Experimental results indicate that although the vibration modes are well separated, the resulting eigen frequencies are slightly shifted and the damping ratios are found higher compared to those estimated by the conventional one point random excitation method. | |||||
