摘　　要：为保证在输送机启动瞬间提高张紧装置的动态响应,以减少输送带磨损,提高输送带使用寿命,介绍带式输送机液压张紧装置的工作原理,建立液压张紧装置AMESim仿真模型,仿真结果表明增加了液压泵排量和蓄能器容积,增大了蓄能器充气压力和输送机启动前蓄能器压力,可以有效降低松边胶带张力和系统的响应时间,其中以液压泵排量和蓄能器容积对其影响较大。In order to improve the dynamic response of tensioner at the starting moment of belt conveyor,reduce belt wear and extend its service life,introduces the working principle of belt conveyor＇s hydraulic tensioner,the simulation model is established based on AMESim.The simulation results showed that the increasing of pump delivery,accumulator volume and pressure,the accumulator pressure before the conveyor starting could effectively decreases the tension drop in the loose belt and response time of the system.The influences of pump delivery and accumulator volume are more evident than others.
