Chain salvage device is a special salvage equipment. It is mainly suitable for shallow seawater salvage and river salvage.The device adopts mechanical hydraulic synchronous circuit and load-sensitive system. It can not only meet the requirements of simultaneous action of multiple actuators,but also improve system efficiency and reduce fever.The hydraulic system was taken full account of the influence of the barge caused by the sea wave heave motion.The system was used of the accumulator passive wave compensation for absorbing the concussion. At the same time, the dynamic analysis of the system was carried out, and the mathematical model was established. Through the simulation of MATLAB/Simulink, the accumulator station is designed.The influence of great changes in stretching and pulling forces of the barge caused by the sea wave heave motion is effectively reduced,which makes the salvage process more stable and reliable, and ensures the safety of the salvage process.
