摘　　要：传统拖拉机在进行农田作业时主要依靠手动控制耕作深度等技术参数,导致耕作误差较大。针对以上问题,研发了一种三点式双作用拖拉机液压悬挂系统,基于双PID控制算法对关键电路部件与控制方案进行设计与选型,并基于MatLab分析拖拉机后悬挂电液控制技术的工作特性。田间试验结果表明:设计的拖拉机后悬挂电液控制系统可以满足田间农业生产要求。Traditional tractors in agricultural operations mainly rely on manual control of technical parameters such as tillage depth,and field tillage errors are large.In response to the above problems,this study develops a three-point double-action tractor hydraulic suspension system,designs and selects key circuit components and control schemes based on dual PID control algorithms,and analyses the working characteristics of the tractor rear suspension electro-hydraulic control technology based on Matlab,and verifies them through field tests.The results show that the tractor rear suspension electro-hydraulic control technology designed in this study can meet the requirements of agricultural production in the field.
