- Abstract
In order to deeply study the flow induced vibration of the gate, this study took the actual project as an example, combined with the two-way fluid solid coupling theory, established a finite element model to analyze the impact of the gate opening on its displacement and stress. The research results show that when the relative opening size is 0. 3, the maximum stress of the gate is at the highest, that is 185MPa, and with the increase of the opening, the maximum stress of the gate also shows a gradual decrease trend, the amplitude of gate stress change is smaller;when the relative opening is 0. 1, the maximum displacement of the gate is the highest, that is 4. 609mm. As the opening continues to increase, the maximum displacement of the gate also shows a gradually decreasing trend. However, the peak displacement when the relative opening is 0. 4 is only smaller than that when the opening is 0. 1, which is higher than the peak displacement when the relative opening is 0. 4. The gate displacement is always in the process of changing when the relative opening is 0. 4. In addition, the peak displacement is also larger than that when the opening is 0. 2 and 0. 3. The stress and displacement of the gate are in continuous change when the opening is 0. 4, which indicates that the risk of this working condition is high. When the door is closed at this opening, it is necessary to pass quickly without staying for a long time.
