摘要
根据刨运机组推移机构液压系统的工作原理,在AMESim液压仿真软件中建立了液压系统仿真模型;针对乳化液弹性模量、负载、背压等影响推移机构液压系统运行的主要因素,在实际允许范围内改变其数值,对推移机构液压系统的动态特性进行仿真,得出各因素对液压系统动态性能的影响程度,并提出相应的系统性能改进措施。
According to working environment of hydraulic system of pushing mechanism of coal plough and convey unit,a simulation model of the hydraulic system was built in AMESim hydraulic simulation software.Dynamic characteristics of the hydraulic system were simulated by changing value of main influence factors of the hydraulic system including elastic modulus of emulsion liquid,working load and loop back pressure in practical scope.According to simulation results,influence degree of each factor on dynamic performance of the hydraulic system was analyzed,and corresponding improving measures for system performance were put forward.
