THE STRUCTURE DESIGN AND APPLICATION OF COMPOSITE ANTI-COLLISION FENDER
摘要
Abstract
This paper sets composite anti-collision fender as the research object.By using Finite Element Method,the dynamics of ship-bridge collisions with different bow shapes were studied,which provides a theoretical basis for the structure design of anti-collision fender.By comparing impact test with numerical simulation results from ANSYS/LS-DYNA software,it improves the finite element model of the collision fenders.Then,three structural types of composite anti-collision fenders are designed,which are D-type and L-type.And the date of collision force,energy dissipation and indentation were from the simulation of the collision among 1000 DWT wedge bow ship,3000 DWT bulbous bow-shaped boats and three structural type fenders by ANSYS/LS-DYNA.Both structure types of collision fenders' adaptability of different shapes are comparatively analyzed.The results showed that the D-type fender protected the wedge bow boat better,but it cannot protect bow-shaped boat.The L-type fenders dissipated energy well for the two kinds of ship,which plays a role in protecting bridges and ships.Therefore,in practical engineering,many factors should be taken into consideration in order to choose the most reasonable anti-collision fender structure.So far,the L-type collision fender has been applied in the Hong Kong-Zhuhai-Macao Bridge protection works.It effectively prevents the risk caused by ship-bridge collision,and provides an important model to promote the application of composite anti-collision fender.关键词
