转筒式钢⁃复合材料套箱是一种新型防船撞设施。采用PATRAN软件建立该新型防船撞设施及船舶的精细化有限元模型,并采用LS⁃DYNA软件进行动力响应分析,基于“分层耗能”的优化思想对该新型防船撞设施进行参数优化,并设置了船舶正撞和15°斜撞两种对比计算工况,选用3000DWT典型代表船舶以4.0 m/s初速度进行数值仿真计算。结果表明:套箱内部竖向和横向板件布置间距为0.8 m、钢板厚度为8 mm时,套箱的船撞力折减率为47.3%,损伤变形量为1.42 m,综合防船撞性能比其他布置形式更优;设置外层护舷层和中间钢结构层不同的厚度比例计算工况,当两者厚度比例为1∶1时,套箱的船撞力折减率为48.9%、损伤变形量为1.27 m、总造价为185万元,在总造价最低的同时其防船撞性能最优;碰撞结束后,正撞工况下船舶的初始动能全部转化为其它形式的能量,而斜撞工况下仍有50%左右的初始动能停留在船舶上、船舶可继续航行,碰撞造成的船艏损伤变形量分别为3.8、0.4 m,则该新型防船撞设施能通过自身旋转拨转船头,大大降低了碰撞造成的船艏损伤程度。
The rotary cylinder steel typed composite boxed cofferdam is a new kind of anti-collision device. The software PATRAN was included to build the refined finite element model of the anti-collision device and ships. In addition, the software LS-DYNA was adopted to conduct dynamic response analysis. The parameters of the device were optimized based on the optimal theory of layer dissipation. In addition, two collision scenarios including front crash and oblique crash were analyzed in this paper. A typical ship of 3000DWT with an initial speed of 4.0 m/s was involved in the numerical simulation. Results show that the boxed cofferdam has a better anti-collision performance when the vertical spacing and transverse spacing of the inner stiffening rib are both 0.8m and the thickness of the steel plate is 8.0mm. At that time, the reduction rate of the collision force on the boxed cofferdam is 47.3% and the damage deformation is 1.42 cm. The working conditions with different thickness rates of the outer fender layer and the inner steel structure were conducted. Results indicate that the boxed cofferdam achieves optimal anti-collision performance with the thickness rate is 1 to 1 at the lowest cost of 1.85 million yuan. At this time, the reduction rate of the boxed cofferdam is 48.9% and the damage deformation is 1.27 m. The initial kinetic energy transfers totally to other types under the condition of front crash collision while there is still 50% of the initial kinetic energy in the ship under the condition of oblique crash. The damage deformations at the vessel bow under the two conditions are 3.8 m and 0.4 m, respectively. This new kind of anti-collision device can greatly reduce the vessel bow damage by self-rotation.
