摘要
针对6 000 m中国大洋多金属结核采矿系统,提出了一种动力吸振器与蓄能器复合作用的升沉补偿系统。分析说明了系统的组成及工作原理,建立了系统的数学模型;应用M atlab编程计算得到了动力吸振系统中吸振器的质量、弹簧刚度和阻尼系数;对系统进行了控制效果仿真研究。研究结果表明,在整个四级海况下,动力吸振器与蓄能器复合作用的升沉补偿系统能得到很好的补偿效果。
A heave compensation system compositely acted by dynamic vibration absorber combined with the accumulator is proposed according to the requirements of 6 000 m deep sea poly - metallic mining system. The composition and principle of the heave compensation system is described, and a corresponding mathematics model of this system is built. The main parameters of the main system are selected. The mass of dynamic vibration absorbe, spring stiffness and damping coefficient are simulated and calculated by Matlab. The simulation study of the heave compensation system is conducted. The results show that the satisfactory control effectiveness can be obtained on the whole condition of sea state 4.
