Research On Vibration Analysis Of Container Lashing Bridge

With the development of shipping industry, container ship is more and more popular for international transport market. Because it has the characteristics of fast loading, high speed, safety and so on. It has become one of the main form for international shipping market. However, the container ship is a kind of special ship types. Its structure stiffness is directly influenced by large opening. In addition, because the deck is stacked multi-layer container, the height of the superstructure also increases. Therefore the superstructure stiffness is led to reduce. So the vibration of the container ship is more prominent, resulting in lashing bridge vibrated too.When the ship is sailing on the sea, lashing bridge will has different degrees of vibration. The vibration of lashing bridge will high cause stress crack or fatigue failure, which poses a great threat to the security of the structure. In addition, the rigging of lashing will be slackened, resulting in the fail of lashing. Therefore, the goods may fall into the sea, influencing the sailing of the state of a ship. The consequences would be too ghastly to contemplate. Thus, to study the vibration analysis of container lashing bridge is very necessary.This paper combined the shipyard actual products, is to carry out targeted market and technology research. With the design method and the advanced design method, it is currently engaged in modeling from the design point of view for the container lashing bridge by ANSYS. Then compare their natural frequency and excitation frequency, Whether they conform to the requirements. If the result is not ideal, to modify the design for container lashing bridge. And the vibration analysis will be done again.
