摘要
所研制的电液控制元件性能检测系统，可完成多种类型的伺胞阀、比例阀、Ｐ－Ｑ阀的动态特性、静态特性自动测试，检测系统中采用有效的抗干扰设计和数字量在线校准模拟量技术，液压系统中采用恒压差闭环调节技术。
A performance test system for electrohydraulic control valves has been develop-ed. lt is applicable for testing the characteristics of different kinds of servo, proportionalor P-Q valves. A design of reduced noise is established and measures for calibratingdata from analog signal channels utilizing those from digital chanels are adopted. Feedback regulation under constant differentia pressure is adopted in the hydraulic system.The test softwrare runs in a Windows enviroment.
