摘要
以1万m3内河小型LNG运输船为例,探讨船舶碰撞数值仿真方法的分析过程和方法,获得该船与不同排水量撞击船相撞时临界撞击速度与撞击角度的关系曲线,根据计算结果对典型LNG运输船的安全运营给出意见和建议。
Taking the 10 000 m3 inland LNG transport ship as example, the methodology of numerical simulations for ships＆#39;collision is discussed.The critical collision speed-collision degree curves for the 10 000 m3 inland LNG transport ship collided by a ship with different displacements are obtained by the non-linear FEM analysis.According to the analytical results, some comments and suggestions for shipping safety of typical LNG transport ship are put forward.
