液压锤中换向滑阀芯液动力的计算

Analysing Flow Force of Directional Control Valve in Hydraulic Hammer and Properly Choosing Directional Control Valve

推导了液压锤中换向滑阀的液动力公式 ,对其内部流道流场进行了模拟和仿真 ,并对仿真结果进行分析 ,得出了影响换向滑阀性能的主要因素 ,有利于合理选择。

This paper deduces a formula of directional control valve in hydraulic hammer and it carries though simulation and imitation inside the flow pipe. We get the main factors affecting directional control valve performance by analysing result. It will help us to design, choose and apply the directional control valve.
