The problem of hydrodynamics and the collision dynamics of the impact beam were analyzed. The nonlinear hydrodynamic equations were established and the frictional resistance between the water body, the vessel and the hull was taken into account , While taking into account the error that would be caused by the assumption of non-stick and non-rotating; the design scheme and the corresponding dynamic problems of two kinds of impact beam with buffer oil cylinder and plastic simply supported beam are analyzed, and the dynamics of lifting and lowering state of the load- The dynamic modeling of the mechanical system should consider the mechanical transmission gap and manufacture the installation error. The SIMULINK simulation main driving system provided by MATLAB is proposed and integrated with the main lifting system and the wire rope bearing sub-system to form a whole model to analyze the electrical How the parameters affect the dynamic performance
