Abstract: According to the analysis of the skid-steer loader working system operation cycle, the working mechanism of self-level valve was elaborated, and the basic principle of achieving the functions of flow rate distribution ratio was discussed theoretically. Based on the comparison of experimental and simulation data, a reliable simulation model of the self-level system was established. The research proved that scaled-up diameter of the fixed and adjustable orifice is propitious to improve the dynamic characteristics of the system. In addition, decrease of the diameter of unloading valve orifice, or increase of the diameter of orifice properly, can reduce the system gain and improve the system dynamic response performance.

Key words: fluid power transmission and control, hydraulic technology, self-level valve, dynamic response, simulation analysis
