实船撞击实验防撞装置的撞击力分析

实验研究了基于以钢丝绳为基本元件的新型柔性防撞装置的防护性能.利用DEWETRON数据采集仪及多通道同步采集传感器的信号,分析得到防撞装置在碰撞中受到的撞击力曲线.实验结果显示:靠近船舶撞击侧最近的非撞击侧位置受到的撞击力最大,属防护重点部位;在承受多次撞击后,防撞装置基本完好,且船舶在碰撞中的损伤也有所减低.

Research on Impact Force of Protection Device Based on the Real Ship Collision Experiment

Wire rope has been used as a new type of flexible protection devices in ship-bridge protection design.In this report,the data of sensor signal are collected in a real-time manner using the DEWETRON data acquisition instrument.Based on the acquired data,the impact force of the protection devices employed in the accident of ship-bridge collision is computed.The results show that the impact force of the Closing to the ship hitting the side of the non-impact side position is the most,it belongs to the protection key positions;and the protection devices are found to be capable of effectively protecting the bridge meanwhile reducing the damage of ship to the minimum.Under repeatedly crash tests,the protection device is noted for its rigidity against collision with little deformation,and ship collision damage has also been reduced.
