컴퓨터 시뮬레이션을 통한 도개교량 종동부 브라켓의 안전성 해석 Safety Analysis of Bascule Bridge Follower Bracket Through Computer Simulation
pp.205-210
In this study, computer simulation of the drawbridge structure was performed to verify the validity of the design and to evaluate its safety. For this, the follower bracket was modeled, and the parts of the follower bracket were connected using 1D elements. The boundary condition applied moments to the rotation shaft of the girder gear in the clockwise and counterclockwise directions, and the connection between the upper parts was modeled using 1D elements to model the bolted connection. In case of rotational shaft deformation, an analysis was performed on the displacement occurring in the structure during the opening/closing operation. As a result of structural analysis of the follower bracket for various cases, the stress at the connection was lower than the tensile strength and yield strength, so it was evaluated as safe. Through this, we intend to use it as a data that can identify anomalies.
