直动型气动电磁阀综合性能测试系统研究

针对目前国内对直动式气动电磁阀测试存在的不足问题,采用高速数据采集系统,应用计算机控制技术,设计了电磁阀综合性能检测系统.测试项目主要有动态特性检测、密封性检测、疲劳寿命测试,并首次引入了最低先导压力的测试,突破了以往只针对单个参数测试的局限.为验证系统的准确性,设计完善了一种基于MATLAB/Simulink的电磁阀动态仿真模型,可应用于电磁阀设计时的多参数仿真和优化设计.运用仿真模型和测试系统,测试、分析了气路压力条件对电磁阀性能的影响,确定了电磁阀测试或使用时的最佳气路压力条件.实验结果表明:该系统能很好地对电磁阀的综合性能进行评判,系统时间分辨率达到0.1ms,压力分辨率0.1 kPa.

Study on integrative performance test system for direct-driven pneumatic solenoid valve

To solve the problem of measuring solenoid valve at present,an integrative performance test system for solenoid valve was designed using high-speed data collection system and computer control technology.The test items for solenoid valve mainly are dynamic characteristic,sealing performance and fatigue life test,and the minimum pilot pressure test is introduced for the first time,which breaks through the limitation that only single parameter of solenoid valve was tested formerly.To verify the system accuracy...
