E-type self-sealing water seal has been widely used in sealing devices of high head and ultra-high head gate,and its sealing performance is greatly affected by the shape of the head.In order to explore the influence of shape on the sealing performance of E-type water seal,the simulation analysis of E-type self-sealing water sealing device has been carried out based on nonlinear finite element method.Firstly,the Constitutive parameters of the Mooney-Rivlin model of the water seal material has been obtained by fitting the test data of the water sealing material.Then the finite element model of E-type water seal has been established and the results of finite element simulation has been compared with those of water seal model test to ensure the accuracy of the finite element simulation method.Finally,the E-type self-sealing water seal with different head radius and head eccentricity under different working conditions is subjected to corresponding loads and constraints,and the finite element simulation is carried out to obtain the contact stress,contact width and deformation of the E-type self-sealing water seal with different head radius and head eccentricity under differ-ent working conditions.Through the analysis of the simulation results,it is obtained that the water sealing performance of E-type self-sealing water seal is affected by the radius and eccentricity of the head.
