The variation law of main parameters on hydraulic steering of articulated dump truck

The steering smoothness of articulated dump truck is impacted directly by the flow, pressure and power of the hydraulic system. The main parameters of hydraulic steering system were studied by mathematical analysis and calculation in this paper. The results show that articulated dump truck constant power hydraulic steering system should be used to maintain a uniform steering. Research results provide a mathematical model for system simulation and a theoretical basis on design of the hydraulic system.
