电液比例伺服阀特性自动测试系统设计

Design of automatic testing system for the detection of characteristics of electrohydraulic servo valve

电液控制系统控制策略的决定与该组成系统的重要环节——电液伺服阀的静动态性能有着密切关系 ,因此 ,有效方便地检测出电液伺服阀的静动态特性有着实际意义。为准确地检测出精校机用电液伺服阀的静动态特性 ,特研制出一个专用的单片机自动测试系统。目前该自动测试系统已成功地用于精校机用电液伺服阀的静动态性能检测。使用表明 ,此自动测试系统具有操作简单、对测试环境要求低、可靠性好的特点 ,能满足电液伺服阀静动态性能的自动检测要求。

The determination of the controlling method of the electrohydraulic control system has close relation with the static and dynamic characteristics of its electrohydraulic servo valve,so it is of practical importance to detect the static and dynamic characteristics of the servo valve efficiently and conveniently.In this paper,an automatic testing system is developed to detect the static and dynamic characteristics of electrohydraulic servo valve in precise straightening press.The automatic testing system has been very successful and shows many good characteristics,such as simple operation, high reliability but low requirement of environment conditions.
