Simulation Analysis of Electronic Hydraulic Hitch System Based on SimulationX

The importance of tractors in agricultural production is becoming more and more obvious. In order to improve the cultivation quality of tractor hitch system, the working principle of tractor hitch mechanism is analyst. A simulation model of mechanical and hydraulic system of hitch mechanism was established in SimulationX. The automatic position control simulation of the hitch system was carried out based on the proportion integral derivative (PID) control strategy. Through the simulation and analysis, the results verify that the model is correct, the automatic position control system of tractor hitch system has good response characteristics, which provide a new method for the design and research of the tractor electronic hydraulic hitch system.
