摘　　要：设计了3种电磁阀电流驱动,试验研究不同电流驱动对电磁阀响应性、阀落座速度、反跳高度的影响,并计算分析了各电流驱动对电磁阀能耗的影响,分析结果表明:电磁阀电流驱动对电磁阀响应性、能耗、阀落座速度及反跳高度等皆有重要的影响,较短的电流上升时间和较高的电流峰值会缩短电磁阀开启响应时间,但是也会增加电磁阀的损耗功率;较高的驱动电流峰值会使阀的落座速度和落座后的反跳高度增加,阀回位过程主要由电磁阀回位弹簧控制,较高的保持电流会使阀的关闭响应降低,保持电流对阀的回位冲击速度没有明显影响。Three current drives for VVA solenoid valve were designed.Simulation and test were carried out to investigate the effect of different current drives on solenoidvalve response,valve closing velocity,bounce and energy consumption.The results showed that current drives had great influence on them.Shorter current rise time and higher peak current can improve open response,but it will lead to higher energy consumption.Higher peak current increase valve closing velocity and bounce height.Valve close was mainly controlled by return spring.Higher holding current can increase close response time and holding current has not much more effect on valve return impact velocity.
