摘　　要：针对中小型拖拉机耕深控制系统精度较低的问题,本文设计了一种新型拖拉机电控液压悬挂系统。以AMESim软件为平台,搭建拖拉机电控液压悬挂系统的仿真模型,通过Adams建模仿真软件建立1L-225型犁具悬挂模型,并进行特性分析,得到犁铧耕深与液压缸位移的变化曲线、犁铧水平受力与力传感器受力和液压缸受力的变化曲线,在土壤扰动工况下进行模拟仿真。仿真结果表明,在土壤不平度的扰动下,该悬挂系统的耕深误差在1.7%以内。该设计提高了拖拉机悬挂系统耕深控制的精度,满足拖拉机犁耕作业的实际要求。A new type of electronic control hydraulic hitch system is designed for the small and medium sized tractor which has a problem with low accuracy of position deepness control system in this paper.Firstly,the simulation model of electronic control hydraulic hitch system of the tractor is built based on AMESim.Secondly,the 1L-225 plough hitch model was built by Adams,and the features were analyzed,getting variation curve of plowing depth with displacement of the hydraulic cylinder,and variation curve of ploughshare horizontal stress with force sensor stress and hydraulic cylinder stress.Finally,the simulation is carried out under the soil disturbance condition.The results showed that position deepness error of the hitch system is within 1.7%under the disturbance of soil roughness.The design improves the position deepness control system of tractor hydraulic hitch system and meets the practical requirements of the tractor ploughing.
