Abstract

In study of hydraulic synchronizing lifting salvage, the mechanical model of the shipwreck under the three conditions (uprighting, lifting and coming out) was established according to the characteristics of uprighting and lifting. Taking a shipwreck as an example, the interaction between the shipwreck and barges was simulated by the multi-body module of GHS, as well as the changes of grounding forces, lifting forces, the maximum longitudinal shear and maximum longitudinal bending moment. Research show that the pose change of shipwreck, the weight distribution, the positions of grounding points and lifting points will have an impact on the lifting forces. In addition, the maximum shear and maximum bending moment will increase during the salvage.

Key words： hydraulic synchronizing; wreck salvage; GHS software; lifting force; grounding force
