摘要

提出了直接基于负载控制阀内异形槽参数的流量控制性能建模方法。流量控制是负荷控制阀的关键性能，它直接决定了系统的可操作性。为了获得更好的比例流量控制能力，负载控制阀的通孔通常设计成不规则形状的凹槽，这增加了阀的建模难度。首先对异形孔进行了几何计算。其次考虑了各部件和各孔的受力平衡和电路计算。建立了直接基于先导孔和反馈孔槽参数的模型。最后，通过实验验证了建模方法的正确性。负载控制阀流量控制性能建模方法可为其它液压阀的建模提供指导。

Flow Control Performance Investigation of a Load Control Valve Using Modelling Method Directly Based on Irregular Shaped Groove Parameters

This paper presents the modelling method of flow control performance directly based on irregular shaped groove parameters in a load control valve. Flow control is the key performance of load control valve because it directly determines the operability of the system. For better proportional flow control ability, the orifices in load control valves are usually designed as irregular shaped grooves, which increase the modelling difficulty of the valve. Geometrical computation of the irregular shaped orifices was firstly conducted. Force balance and circuit calculation of the components and orifices were secondly considered. The model that directly based on the groove parameters of the pilot orifice and the feedback orifice were obtained. Finally, the modelling method was validated by experiment results. The modelling method of load control valve flow control performance can provide guidance for the modelling of other hydraulic valves.
