The dynamic response of the honeycomb plate structure was characterized in terms of modal parameters at different micro-vibration level. Two main sweep test methods were established on the ground to measure the FRF curves of a combined plate structure jointed by bolts, over a range of vibration acceleration from 10-1 g to 10-6 g, by which the natural frequencies and damping ratios were obtained. The results showed that the variances of the first three natural frequencies were less than 1% on different acceleration levels, and the variances of damping ratios for the first three modes are less than 25%.
