Abstract


Now with the demanding of energy continues to heat up in the worldwide more and more countries take the Marine energy as the core areas of the new century energy strategy.The crane ship is a vital special equipment of marine engineering and application,and the applications and technologies more and more be concerned and researched.Due to the particularity environment the crane ship work on it will cause the violent movement of the hull when in the sea,lifting and other conditions by the wind and waves. Resulting in the irregular large swings of Hanging objects,and severe cases must cease operations.This has seriously affected the crane barge work efficiency, and increased operating costs.And the amplification of power load by the swing back and forth of hanging objects have a greater impact on the security of the crane structure,and so how to qualitatively analyze the swing of hanging objects and to find methods to reduce the swing of hanging objects are the important part of the crane ship research.A numerical study of the hanging objects space swing based on the multi-body dynamics theory and consider the case of hull movement and operation of the crane.First,build a theoretical model of the general floating crane with the entire rotation, and derived the relationship of dynamics transform between the hull movement and hanging point movement in the case of considering the operation of the crane turntable and boom operation. Create a nonlinear equation of motion of the hanging objects space swing by Lagrange equation, and have the numerical solution of the dynamic equations by the precise integration method.Last,to apply the proposed method calculate the dynamic response of the hanging objects in a large semi-submersible floating crane under different sea conditions, and analysis the sling dynamic tension changes.
