Research on Steering Vibration Analysis of Wheel Loader and Cushion Valve Design

At present, the wheel loaders on market have steering vibration problems, which can be summarized as follows: front frame and cab vibrate violently at beginning end of steering. This paper analyzed mechanism by collecting pressure different positions hydraulic system AMESim simulation. A cushion valve was designed to solve problem vibration. Finally, prototype test carried out it concluded that reduced starting shock 50%, stop 75%, suction no longer occurred. Further, analysis provides theoretical experimental basis for research loaders, also new ideas design optimization vehicle systems.
