摘要
为进一步研究半主动式升沉补偿的补偿工作机制,在对半主动式升沉补偿装置补偿原理分析的基础上,对装置中的气液储能器和主动补偿缸进行了力学分析和流量连续性分析,并基于AMESim软件对补偿系统进行建模和仿真分析。结果表明:补偿过程中大钩位移随时间变化范围较小,处于小幅值正弦波动范围内,系统能耗曲线近似呈线性上升趋势以及气液储能器压力曲线变化整体趋于平稳。该系统仿真结果能为半主动式升沉补偿装置的设计改进和技术发展提供参考,进一步提高系统的补偿效率和降低能耗。
In order to further study the compensation mechanism of semi-active heave compensation,based on the analysis of the compensation principle of semi-active heave compensation device,the analyses of mechanics and flow continuity of gas-liquid storage devices and active compensation cylinder was carried out. The AMESim software was accepted for the modeling and simulation analysis. The result shows that the variation range of compensation process of large hook displacement is in a small amplitude of sine wave when the time changes. The system energy consumption curve is approximate to linear upward trend and the pressure curve of gas liquid accumulator overall tends to leveled off. The system simulation results of semi-active heave compensation device can be used as the reference for improving the design and developing technology of the system of compensation efficiency and reducing energy consumption.
