Abstract:
Based on the desulfurization tower of 300 MW unit, authors studied the fluid-solid coupling dynamic characteristics of the large thin-wall structure by inputting the sine wave and earthquake wave in different acceleration peak values. A 1:15 scaled steel model of desulfurization tower was tested on shaking table and authors compared the results with the non-liquid states. The results show that the responds of fluid-solid coupling acceleration peak values of the desulfurization tower is less than the case without liquid under the same acceleration peak values of sine wave. With the change of the input dynamic wave, the dynamic responses of the structure will change correspondingly. The fluid-solid coupling responses of structure are different from the non-liquid obviously. It provides an experimental basis for further studying of fluid-solid coupling dynamic characteristics of thin-wall openings structure under different seismic waves and the establishment of related specifications.
