| Abstract: | Finite element model was set up in terms of the characteristics of the structure and loads,considering the nonlinear frictional contact between the bearing nest and mushroom ball.Based on the simulation of the diagonal brace＇s prestress debugging process,the influence of the prestress of the diagonal brace upon the structural torsional stiffness was discussed.The quantitative assessment was made to the static response and dynamic characteristics of the miter gate,and the optimization scheme was proposed. |
