深水勘察装置波浪补偿系统设计

摘要

分析了装置总体结构的工作原理及功能要求.基于位移型升沉补偿策略设计了油缸和蓄能器相结合的波浪补偿系统,并对油缸补偿系统部分进行受力计算.根据受力方程建立了系统的数学模型,应用MATLAB分析工具进行了系统仿真.系统能满足浪高6m、周期12 s的海况条件,最大升沉补偿速度达到1.5 m· s-1,最大补偿功率600 kW.%The working principles and functional requirements of entire structure are first analyzed. Then,the wave compensation system,which consists of the cylinder and accumulators designed via the displacement sinking compensation strategy with loading calculation. Based on the mathematical model of loading function,the system simulation is next conducted using Matlab(TM) analysis tools. Finally,it is found that the system can satisfy the sea conditions of 6 m wave-height and 12T s period, together with 1.5 m · s-1 maximum compensation rate and 600 kW maximum compensation power.
