摘要
以某双滑道纵向倾斜船台下水载重38800t散货船为例,通过理论计算及有限元法分析,仅对船体下水时的艉部受力情况进行分析,提出横梁的布置方法,并对其结构强度进行计算。结果表明:布置方案能满足船舶船台双滑道下水的要求,为滑道下水方式的艏艉部横梁布置提供参考。
Taken a deadweight tonnage 38 800 t double slide way launching bulk carrier as an example, through the theoretical calculation and finite element method (FEM), the hull force situation is analyzed, the layout method of beam is put forward, and the structural strength is calculated. The results show that the layout scheme can meet the requirements of ship longitudinal double slide way launching, and provides guidance for launching beam layout way.
