Description
Technical field
The invention belongs to field of ocean engineering, more particularly to salvage technology, and in particular to simulated dual barge is same
Walk the hydraulic pressure heave compensation test platform of lifting.
Background technology
In recent years, as the continuous development of China's ocean engineering, Description of Ship are on the increase, especially large-tonnage ships number
Amount is obvious to be risen, once shipwreck, marine emergency rescue fishing is just particularly important.Wherein, hydraulic synchronizing lifting
Nowadays system is widely used among all kinds of refloating operations as one of big, efficiency high fishing operation of contributing.It is however, extra large
Upper engineering is different from land, and it is carried out on barge, due to the presence of sea situation, in work progress, barge can produce with
The wave motion of machine, there is the phenomenon of wirerope unbalance stress, therefore Synchronous lifting process is difficult to ensure that, more dangerous situation is exactly
Cause the generation of marine accident, in order to solve this problem, people begin one's study the work of heave compensator during Synchronous lifting
With and how it is efficient carry out heave compensation, the test platform of simulated dual barge synchronization lifting system has been built for this.
In the prior art, there is a kind of simulation experiment platform on barge heave compensation.Experiment porch is simulated including barge I
Steel plate, barge II simulate steel plate, shipwreck simulation steel plate and two analog motion platforms, and barge I simulates steel plate and barge II is simulated
Steel plate is separately fixed in two analog motion platforms, and the analog motion platform that carrying barge I simulates steel plate is six degree of freedom fortune
