In order to improve the anti-impact ability presented by optimizing the parameters of its hydraulic of its hydraulic steering system, a method is components for increasing the steering control ability of a vehicle in the off-road condition. An AMESIM model is established for the hydraulic dynamic characteristics of the system, and the factors affecting the anti-impact ability of the system are analyzed. The results show that such measures as improving the stiffness of its high pressure pipeline, shortening the length of the lines, increasing the flow of the steering pump, and shortening the kingpin offset can enhance the impact resistance of the system.
