拖拉机悬挂系统电液控制的理论和实验研究

THEORETICAL AND EXPERIMENTAL RESEARCH ON A TRACTOR LIFT SYSTEM FOR ELECTRONIC-HYDRAULIC CONTROL

分析了江苏－５０及同类型拖拉机悬挂系机液动力装置的非随动、继电开关型特性，并以此为基础，建立了该装置电液控制实验系统。通过实验、分析，得出一些有益的结论。

The paper analyses the on-off characteristics in adjustments of a hydraulic suspend devicefor JIANGSU-50 and in analogous to it tractors. On the basis of theory to set up electronic-hydraulic experimental system of on-off control model about above-mentioned device. Bymeans of monolithis-microprocessors and digital error control technic,relative hardwareand software are made and experiments are conducted in room.Researched into experimentalresults,some very useful conclusions have been drawn.
