| description | In order to study the change law of mechanical characteristic parameters of the steel spherical hinge of swiveling bridges in the process of rotation, a T-shaped rigid swiveling bridge over railway is used as a research target in this paper, and a three-dimensional bridge finite element model was constructed. The process of bridge turning was numerically simulated by Ansys software(Ansys Release 16.0); the patterns of change in the upper turntable and steel spherical hinge stresses for specific rotational angles were obtained, the effect of bias loads on the stress distribution in the upper turntable and steel spherical hinge was analyzed, and the stress data of the steel spherical hinge of numerical simulation and real-time monitoring were compared. The results illustrated: During rotation, the maximum compressive stress in the upper turntable is located in the contact area with the outer edge of the upper steel spherical hinge; the maximum compressive stress in the steel spherical hinge is at the edge of its own circumference. The overall stress in the upper steel spherical hinge is slightly greater than the stress in the lower steel spherical hinge. Under the eccentricity condition, the maximum compressive stress in the steel spherical hinge increases with increasing eccentricity, and the stress concentration is more significant. The eccentric limit position of swiveling bridges is determined by the strength of the upper turntable. The monitoring method of deploying stress gauges at the steel support structure of the lower bearing platform provides a new method to obtain the stress pattern of the steel spherical hinge and even the bridge as a whole. |
