Paper Title:
Digital Electro-Hydraulic Proportional Control for Bulldozer Working Device
  Abstract

In order to improve the steering and braking of the bulldozers, electro-hydraulic proportional control technology is adopted without change the transmission system of bulldozer, two hydraulic rams are used to control the steering and braking valves in both sides of bulldozer, one electromagnetic direction valve to select controlling side, and proportional reduced valve to control the pressure of hydraulic ram. Then Matlab/Simulink to imitate the dynamic characteristic is used, The single stick steering and braking control system designed improve the maneuverability and operating condition of bulldozer. The result of this paper can apply to practice directly and use for reference for other engineering machine as to single stick centralized control.
