Structural Optimization Design of Flexible Anti-Collision Device for Bridge

Abstract:

Due to he complexity of the shipping collision process, the design of the protection device can not be accurately calculated by theoretical formula. Through the establishment of the anti-collision device in simplified model, this paper carries out the simulation analysis of the finite element values, and studies the key parameters that affects the performance of the anti-collision device: the geometric structure of inside and outside of steel, the combination of anti-collision circle (elastic element), the flexural rigidity of peripheral steel. And then we get the design parameters of the equivalent flexural rigidity of peripheral steel which is to ensure the that the peripheral steel won’t be partial collapse when there are some collision between some representative ships and it; and we also find that the appropriate increase in the flexural rigidity of around the vertex of the outer steel will improve the overall anti-collision ability of the anti-collision device.
