Research on the Effect of Fluid-Structure Interaction on Dynamic Response of Gate Structure

Abstract:

This essay reveals that on the basis of fluid-structure interaction having appreciable impact on auto-vibration of gate structure, analysis and calculation on dynamic response characteristics of gate structural fluid-structure interaction have been conducted. The results indicate that under the same dynamic load the structural dynamic response value with fluid-structure interaction effect considered is remarkably larger than vibration response with fluid-structure interaction effect considering. The calculating results indicate that the largest response increase of typical parts of gate structure is from 50% to 60%. Therefore, as to making calculations on structural dynamic response with fluid-structure interaction effect, the impact flow field exerting on structural response should be taken into consideration.
