, also in rapid growth, ship collision pier shaft event happens occasionally for position, quantity, speed, and this constitutes very big prestige to the safety of bridge
The side of body；Based on rubber, fiberglass, there is following limitation and defect in it to the more at present anti-collision facility material adopting：（1）Fiberglass
Anti-collision facility：Glass fiber reinforced plastics anti-collision facility fragility is big, and rigidity is strong.When accepting to clash into, in the tolerance range of this kind of material, occur
Largest deformation and counter-force, but because this material reply deformability is poor, destroy hull simultaneously；Upper once clash into when, if
Impact force is identical, then the deformation quantity that material produces is less, and under so repeatedly clashing into, material occurs the minima of deformation quantity,
Until not redeformation, bridge pier can be produced in the case of clashing into again and damage；（2）Rubber anti-collision facility：With collision aggravation, rubber
Glue material matter anti-collision facility can be subject to maximum impact force, be now pressed onto certain limit interior it may appear that a counter-force maximum, companion
The maximum deformation quantity being compressed with the appearance of counter-force maximum, rubber anti-collision facility, then have the elastic process of back-pressure contracting,
But under such shock, rubber anti-collision facility can not reply deformation completely, a relatively low change occurs in springback process
Shape amount and counter-force, after fixing with such deformation value, counter-force effect also no longer changes, and protection effect substantially reduces；In addition,
The Impact energy that existing anti-collision facility can be offset is limited, also there are some simultaneously and is only capable of offsetting from some special angle
The anticollision gear of local impact's energy, thus anti-collision effect is not so good, the protective action being played is limited；To sum up, existing ship
All there is the number of drawbacks such as input cost is higher, service life is shorter, anti-collision effect is poor to some extent in oceangoing ship anti-collision facility
And deficiency.
