In this paper, the DETF with silt structure on the beam is designed and manufactured. The natural frequency of the DETF beam with silts is measured by loading different axial tensile displacement on the DETF beam. The force-frequency characteristics between the axial force and the natural frequency of the DETF beam with silts is obtained and compared with the theoretical results. The experimental results are in good agreement with the theoretical results.
