To ensure the safe and stable operation of large radial gate in service, taking the hydraulic radial gate of Gezhouba Project as an example, the finite element analysis software was used to analyze the static strength and modal to obtain the maximum stress concentration point and deformation of the gate under the design head condition. The vibration intensity of the gate was judged according to the natural frequency, vibration model and maximum deformation displacement. The results show that the deviation between the total design water pressure of the gate and the theoretical calculation is 4.7%, which is located in the 5% error control range. The overall maximum stress of the radial gate is 373.86 MPa and the deformation is 12.938 mm, meeting the design requirements of the specification. The bottom of the panel exists local stress concentration, the overall vibration deformation of the gate is less than 0.508 mm, and the vibration intensity is small. Only low-order frequencies appear in the high-energy region of the pulsating pressure of the water flow, and the possibility of resonance is small.
