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.
