摘    要:针对非通航孔桥墩,研发了一种自适应拦截网防船舶撞击装置,主要由系泊大浮体、系泊锚链和固定锚、自适应小浮筒、拦截网、恒阻力缆绳以及触发钢索所组成。阐述了该防撞装置设计原理,即偏航船舶撞击该防撞装置,小浮筒会带动拦截网自适应地从水平状态竖起展开,包裹住来撞船首,再通过相连浮体的运动阻力和恒阻力缆绳来吸收船舶动能,拦截住船舶,保护非通航孔桥墩安全。随后介绍在福建平潭海峡大桥引桥附近海域实施的实船撞击自适应拦截网防撞装置的大型试验,试验结果显示:自适应拦截网成功升起,船舶被安全拦截,从而实验证实了设计原理与设计方案的可行性和可靠性。最后,采用大型水动力分析软件AQWA对防撞装置拦截船舶过程进行数值模拟,模拟结果与实验结果基本一致,说明了数值仿真具有较好的计算精度和可靠性,能够为该防撞装置的结构设计与优化提供重要的参考。

关 键 词:自适应拦截网防撞装置  非通航孔桥墩  实船碰撞  水动力分析

Abstract:An adaptive arresting net crashworthy device has been developed for protecting non-navigable channel piers against ship collisions, which consists of mooring floating boats, mooring cable and mooring anchors, adaptive floating buckets, arresting net, triggering wire rope and constant resistant force cables. When a ship impacts the adaptive arresting net crashworthy device, one head of the adaptive floating buckets will rise due to the floating force, then the arresting net can capture the ship. Enormous kinetic energy of ship is consumed by a series of resistant force cables failure. The ship collision tests at full scale and hydrodynamic analysis of the adaptive arresting net crashworthy device had been conducted. The motion response of the crashworthy device impacted by ship was observed and discussed. The experimental results show that the arresting net is adaptive and the ship can be prevented successfully. By using hydrodynamic analysis software ANSYS AQWA, a numerical simulation model of the adaptive arresting net crashworthy device is established. The numerical simulation results are in reasonable agreement with the experimental results.
Keywords:adaptive arresting net crashworthy device  non-navigable channel piers  ship collisions  hydrodynamic analysis
