摘　　要：针对6000m中国大洋多金属结核采矿系统,提出了一种带蓄能器的被动升沉补偿系统。为补偿系统的交变应力和载荷,在被动系统的工作原理基础上,设计了系统的主要参数,建立了系统的数学模型。利用仿真软件MATLAB仿真分析了系统主要影响因素,进行参数选取,并研究了系统的控制性能。结果表明,所设计的被动系统对矿区四级海况下,海浪能量集中频段中,有较好的补偿效果;随机波作用下,系统补偿率大于80%。结果为实际被动升沉补偿系统的研制提供了理论依据和技术参考。A passive heave compensation system with the accumulator is proposed according to the requirements of 6000m deep sea poly - metallic mining system. The principle of the heave compensation system is described, the main parameters of the system are calculated, a corresponding mathematics model of this system is built. The parameters which affect the performance of the system are simulated and analyzed by MATLAB. The simulation study of the passive heave compensation system is conducted. The results show that the satisfactory control effectiveness can be obtained on the condition of sea state 4. The compensation rate of the system is higher than 80% under the influence of random wave. The results of modeling and simulation research offer reference of the theoretical basis and technical for the development of passive heave compensation system.
