spool displacement

The results show that the new type of proportional direction valve is of good steady state control characteristics and equal displacement characteristics. The linearity of the control curve of the main spool displacement is well. However, there exists a certain neutral position control dead zone.

研究结果表明，新型比例方向阀的稳态特性和等位移特性良好，主阀芯位移控制曲线的线性度也较好，但有一定的中位控制死区。

The effect of flowrate arises mainly from valves 'pressure drop~ spool displacement static characteristic in the case of small d_x. The result of experiments for the effect analysis agrees with the authors' values.

在小d x区域，流量对阀芯关闭时间的影响主要取决于阀的静态压差&阀芯位移特性，在这些方面试验结果和作者的理论分析是完全一致的。

In this paper, according to the results of previous studies using high-speed switching solenoid valve as a pilot valve control valve spool multiple displacement, the ultimate control of the telescopic hydraulic cylinder.

本论文根据以往的研究成果提出用高速开关电磁阀作为先导阀来控制多路阀阀芯位移，最终控制工作液压缸的伸缩。
