It is further concluded that this study provides a good base upon which an interaction study between other components and the pilot operated reduction valve of a complete hydraulic system can be initiated. The model could be used in predicting trends that could occur under various loading conditions that are difficult to create experimentally. This consideration is important in future expansions of the study to indude the dynamics of the pump and loads.

先导式减压阀的动态分析摘要
这篇文章是通过键图仿真技术来对先导式减压阀进行的动力学研究。该系统的控制方程是从模型中派生的。在求解系统方程的数值解上，通过各种压力阀门的端口确定流动特征考虑。这个仿真研究确定了一些关键的设计参数，并对系统的瞬态响应效果显著。论文网
1 简介
减压阀几乎可以用于每一个液压系统。减压阀的作用是限制存在于系统的最大压力。在理想情况下，减压阀应提供并且替代流动路径的流体，使槽系统在保持系统压力恒定。有两种类型的阀门，直接作用式和先导式。直接式可以打开了减压阀与弹簧预载阀的阀芯。这种阀由于过低的压力过载特性，使用正在逐渐减少。
为了提高这些特点，介绍了样品试制阶段的情况。先导式液压系统可以文持在一个恒定的压力情况，因此该阀被频繁的使用于复杂的液压控制系统。由于少量的液体通过先导阀芯，设定压力可以使阀保持在一定的压力流量下，使特性几乎没有影响。先导型的主要部分和先导阀芯通过液压流体耦合运动使得性能分析更困难。
