Offshore structure anti-collision structure with negative Poisson's ratio effect
The invention discloses an offshore structure anti-collision structure with a negative Poisson's ratio effect, which relates to the field of offshore building safety, and is characterized in that the anti-collision structure is composed of an outer anti-collision plate, an inner anti-collision plate and an energy absorption device between the outer anti-collision plate and the inner anti-collision plate; the energy absorption device comprises a front head-on collision plate, a rear top plate and a negative Poisson's ratio chiral rotating structure in the middle, the negative Poisson's ratio chiral rotating structure comprises a plurality of structural units, the structural units are adhered to one another in the plane direction to form a plane spreading state, and in the vertical direction, the structural units are arranged in a staggered mode. Multiple layers of equal-plane-distance structure unit plane spreading structures are arranged between the front head-on collision plate and the rear top plate, and the structure units are bonded with the front head-on collision plate and the rear top plate; the structure is based on a negative Poisson's ratio structure, the buffering and energy absorbing characteristics of the negative Poisson's ratio structure serving as an anti-collision device are effectively improved through reasonable cooperation of a plastic material aluminum alloy and an elastic material rubber, and therefore the anti-collision performance of offshore structures is improved.
