Finite Element Simulation and Design of Bridge Superstructure against Ship Collision

Abstract:

Bridge in the upper structure of ship collision navigation is typical of ship collision accident. In order to protect the bridge of the upper structure, The design adopt high frame which is fabricated according to the protection devices of elastic-plastic deformation to absorb the hull kinetic energy. Using the general explicit dynamic analysis program LS-DYNA 9.7 for ship collision frame which is fabricated according to the numerical simulation, getting the section size, material properties and the ship speed of the protection devices and ship collision relations between influence. Analysis results could be the design and maintenance reference for the decision-making departments.
