摘要

提出并研究了一种均匀搭接和不均匀搭接的非对称伺服阀。目的是加快气动力控制系统的阶跃响应速度。以一种下游口宽为上游口宽两倍的非对称伺服阀为例，首先重点研究了均匀下搭和不均匀下搭的非对称伺服阀的结构，并对其进行了详细介绍。在此基础上，研究了适用于滑阀不同搭接和不同通口宽比的伺服阀的稳态特性。理论结果与实验结果相当吻合。

Development of an asymmetric servovalve with even underlaps or uneven underlaps

An asymmetric servovalve with even underlaps or uneven underlaps is proposed and investigated. The aim is to speed-up the step response of a pneumatic force control system. By using an asymmetric servovalve whose down-stream port width is twice the up-stream one, first, the structures of the asymmetric servovalve with even underlaps or uneven underlaps are mainly considered and introduced in detail. Next, the steady-state characteristics of these types of servovalves for this approach, which are applicable to different underlaps and different port-width ratios of the spool valve, are investigated. The theoretical results agreed fairly well with the experimental ones.
