基于AMESim的摇臂式清仓机液压系统动态特性的研究

摘要

针对摇臂式清仓机液压系统进行研究，利用AMESim仿真软件分别搭建了液压系统截割回路、支撑回路和回转回路的仿真模型，并对其动态特性进行仿真及分析，得到各回路对应的压力、流量、转速随时间变化的曲线。仿真结果表明：该液压系统具有压力波动小、调速范围广、回转平稳的特点。%To study the hydraulic system of rocker arm type clearing machine , the models of cutting loop , support loop and rotary loop were built based on the simulation software AMESim , and the dynamic simulation of the system was carried out .At the same time , the pressure , flow and speed versus time curves corresponding to various circuits were obtained .The results show that the hydraulic sys-tem has characteristics of small pressure fluctuations , wide speed range and smooth rotation .
