Abstract: Abstract:Using ANSYS software, the static and dynamic characteristics of the gate slot structure of the tail water emergency gate of Qingyuan Pumped Storage Power Station were studied and analyzed numerically. The stress, the displacement, the stability, the free vibration frequency and the vibration mode characteristics were calculated and analyzed. The results in this paper provide the technical basis for selection of final design scheme of the gate slot structure and reference for design calculation of similar gate slot structures.
