摘　　要：通过分析滑移装载机工作系统的动作循环,详细阐述了调平阀的工作机理,并从理论角度论述了其实现流量分配比功能的基本原理。在对比试验与仿真数据的基础上,建立了可靠的调平系统仿真模型。研究表明:按比例增大固定节流孔和可调节流孔的直径,有利于提高系统的动态特性;此外,适当减小卸荷阀内阻尼孔的直径,或增加稳定阻尼孔的直径可以降低系统增益,提高系统动态响应性能。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.
