摘要
近年来船舶撞击桥墩的事故频繁发生,船桥碰撞理论的研究已受到国内外学术界和工程界的高度关注。概述了目前国内外对船桥碰撞的各种计算方法并进行了对比分析。再通过有限元软件ANSYS/LS-DYNA对不同吨位、不同行进速度船舶进行了数值仿真计算,将结果与国内外计算方法进行了对比研究。研究结果显示按各计算公式所得到的结果有一定的差异,且个别差异较大。这种仿真分析为船桥碰撞的理论研究提供一条有效的途径。
In recent years,ship-bridge collision theory has been paid high attention in academic world and engineering field at home and abroad due to accidents of ship-bridge collision occurring frequently.An overview of different calculation methods on ship-bridge collision on domestic and international is provided with comparative analysis.Then the numerical simulation calculation of different speed and weight is provided by Software ANSYS/LS-DYNA and the results are compared and researched with calculation methods at home and abroad.The study results show that every result has certain diversity according to every calculation method with individual larger diversity.In a word,this simulation analysis can provide an effective way to ship-bridge collision theory.
