摘　　要：针对深海多金属结核扬矿泵管系统海上试验时可能存在的紧急排料需求,开展了海上试验系统紧急排料机构液压系统理论计算,并在AMEsim中进行了仿真试验,结果表明,AMEsim仿真软件对于该系统的可信度系数为0.86。基于AMEsim构建了500 m海上试验执行机构液压系统模型,仿真分析结果表明,液压系统中油管管径为16 mm,设定压力应不低于10.47 MPa,执行机构动作时间为6 s。研究结果可为紧急排料机构的设计提供依据。Aiming at potential emergency discharge required during at-sea testing of deep-sea polymetallic nodules lifting system consisting of pipeline and lifting pump,a theoretical calculation was conducted for the hydraulic system of emergency discharge mechanism for at-sea testing,and also a simulation analysis was conducted with AMEsim.It is found that the reliability coefficient of AMEsim for the system is 0.86.An AMEsim-based hydraulic system model was established for the actuator in an at-sea test at 500 m depth.The simulation results show that the oil pipeline in the hydraulic system is 16 mm in diameter,with the set pressure not less than 10.47 MPa,and the action time of actuator is 6 s.This research results can provide a reference for the design of emergency discharge mechanism.
