电磁阀试验台的流体脉动及其消减措施的研究

Fluid pulsation and corresponding elimination measures for solenoid valve test-bed

对电磁阀试验台流体系统产生脉动的原因作了分析与探讨,并应用频率特性分析法对主测试管路的频率特性进行了计算和仿真;在此研究基础上选取最佳的结构和元件参数以及采取相应的消振和滤波措施,可有效地减少和消除流体系统可能出现的压力脉动并避开谐振现象发生。该研究对相关流体控制和测试系统研发中如何避免测试管路谐振现象的发生及消减流体压力脉动和冲击具有一定的工程应用价值。

The causes of pulsation in fluid system of solenoid valve test-bed were discussed. The freque characteristics of main test pipeline were calculated and used in simulation. The optimal parameters of structure ncy and components were chosen and the corresponding elimination measures were taken based on the theoretical analysis. These measures could deduce and eliminate the pressure pulsation effectively and prevent resonance, which can give a reference to similar fluid control and test systems and is valuable to engineering application.
