摘要
拖网被动补偿系统是针对大型拖网渔船上拖网在作业中保持一定的网型而设计的装置。通过介绍拖网被动补偿系统的方案设计和工作原理,分析补偿系统的受力情况,构建重物位移与船体位移之间的数学模型;以及对补偿系统的重物位移和补偿效率进行仿真分析,从而得到蓄能器的体积和船体升沉的周期对补偿系统的补偿效率影响的仿真曲线,这为相关设计人员对拖网被动补偿系统的设计计算提供了理论指导。
The trawl passive compensation system is designed for large trawlers to keep an optimal net type in trawling. Through the introduction of the design solution and working principle of the passive compensation system, the mathematical model is built between an object displacement and hull displacement, based on the force analysis. The simulation analysis is done to the weight displacement and compensation effciency. The simulation curves of the influence of the volume of the accumulator and the hull heave cycle on the compensation efficiency of the compensation system is gained, which provides the theoretical guidance of trawl passive compensation system design for relative designers.
