摘要
采用有限元法对某3 000 t船舶与桥梁防撞护舷碰撞的动力学特性进行分析.通过将护舷试样的碰撞试验与有限元计算结果进行对比,完善该防撞护舷的有限元模型,使其更可靠.用ANSYS/LS-DYNA模拟3 000 t船舶撞击3种不同护舷(D型、圆环型和板型)的过程.不同护舷吸能结果表明:对于D型护舷,船舶会碰到桥墩,失去作用;对于板型护舷,船舶变形严重;圆环型护舷的效果最好.
The finite element method is used to analyze the collision dynamics characteristics of 3 000 t ship while it collides with bridge anti-collision fender. To perfect the finite element model of the anti- collision fender and make it more reliable, the experimental results of the fender sample are compared with the finite element calculation results. ANSYS/LS-DYNA is used to simulate the process of the collision of 3 000 t ship with three types of fenders （D-type, ring-type and plate-type ）. The energy absorption results of these different fenders show that, the ship could impact the bridge pier while the fender is D-type, which would be out of action; the deformation of the ship is serious while the fender is plate-type; the ring-type fender are the best.
