Design of load sensing hydraulic system for European purse Seine transport-roller
摘要
Abstract
The European purse Seine is one of the most efficient purse Seine fishing methods for pelagic fish.The cooperative netting and transmission control technology is studied to ensure the efficient continuous netting operation of the European purse Seine.Based on the adaptation requirements of netting and netting on a new 40 m European Seine model fishing boat,this paper studies the design of the hydraulic transmission control system of the transport-roller by using load-sensitive control technology,constructs a resistance characteristic model of"fishing gear load-netting speed,"and integrates a double closed-loop feedback control system based on hydraulic load-sensitive and electro-hydraulic constant power control.The Seine transport roller is co-controlled to adapt to the fishing gear load,and the AMESim software is used to simulate the load-sensitive hydraulic transmission control system of the transport roller.The simulation results show that the load-sensitive hydraulic transmission control system of the transport roller can adapt to the load change of the Seine netting gear,automatically adjust the netting speed and constant power netting,and realize continuous netting operation.Compared with the traditional hydraulic system transmission of the transport roller,the network efficiency is increased by 32.78%under the same sea conditions.The hydraulic load-sensitive transmission control technology involved in this study provides a solution for efficient fishing in European purse Seine fishery.关键词
