Simulation and Analysis of Passive Rolling Compensation of High Sea Salvage System
Method and device of a flexible interception and salvage system was introduced in this paper.In order to study the effect of wave motion on salvage operation,we proposed a passive wave compensation scheme that utilizes a combination of variable-pitch cylinders and accumulators,and established the mathematical vibration model of the rolling motion of the salvage compensation system.With the relationships between the stiffness coefficient and the accumulator parametric of passive compensated gas-liquid system,we determined the effective compensation stiffness range through Mathematica simulation analysis.The relationship between the roll displacement of the salvage arm and the initial volume V0 of the accumulator has been analysed.The results show that the accumulatorV0 in a certain range has a great influence on the passive compensation.However,when the volume is greater than 20m3,the compensation effect is weakened,and tend to a certain value,irrespective of the passive system accumulator volume capacity,it does not achieve full compensation.The results have important guidance on the design and optimization of rolling passive compensation of the practical high sea salvage system.
