For the purpose of providing useful reference for optimizing the design of Collision-Prevention Device of Bridge Pier, analyzing the collision parameters and putting forward the ideal size of the circular steel tube and angle steel in absorbing energy,the ship impacting the steel tubular truss,which belongs to the Collision-Prevention Device of Bridge Pier, is simulated.The water level of ship and the size of circular steel tube and angle steel are discussed respectively with the ANSYS/LS-DYNA program,which is the nonlinear dynamic analysis software,to study the impact of change of the single collision parameter to the equipment for anti-collision which is the steel tubular truss.when the ship impacts the steel tubular truss under the ideal level,the circular steel tube and the angle steel could play fully in resisting the collision of ship, achieved a better absorbing effect.The circular steel tube can play a chief absorption effect through the bending deformation, while the relatively small energy is absorbed by the angle steel through the buckling deformation. The best sizes selected through the optimum structural design are shown as follows: the diameter of circular steel tube is 800mm; the thickness of tubular wall is 12mm; the size of angle steel is 100mm×100mm×12mm.
