In order to solve the problem that the new hydraulic gate is difficult to manufacture experiment and debug in the real environment, the historical gate operation data was analyzed and transmitted based on the digital twin simulation platform. The designed gate was analyzed through numerical simulation, and the overall stress and deformation changes of the gate with different sub-gate opening degrees under hydrostatic pressure were analyzed. At the same time, the overall vibration frequency changes of the gate under the action of air and fluid-structure interaction were analyzed. The flow state of the fluid domain at the sub-gates with different opening degrees was simulated. The results show that with the increase of the opening of the sub-gate, the stress value of the gate varies from 58 MPa to 67.5 MPa, and the deformation change is not obvious; Compared with the natural vibration frequency of the gate in the air, the fluid-structure coupling effect will appropriate reduce the natural vibration frequency of the gate; Different sub-gate openings will affect the flow state of the fluid domain, and increasing the opening will reduce the water velocity. The results provide some references for its actual operation, maintenance and optimization of gate performance.
