The Design of Swivel Structure for Cross Railway Swivel Bridge
By determining the design load value of the rotating structure through the overall static model calculation of the continuous rigid frame bridge before and after the rotation,and conducting structural calculations on the ball joint,pin shaft,and upper and lower bearing platforms according to the specifications,the rationality of the design is validated by using the three-dimensional finite element software ABAQUS for numerical analysis.The results show that the rotating structure is subjected to overall compression after the upper bearing platform is equipped with bidirectional prestressing.
