| 摘 要： | 建立了音圈电机的数学模型，结合实验测试，对车用音圈式比例减压阀的阶跃响应和频率响应特性进行了研究。结果表明：音圈式比例减压阀阶跃响应速度明显快于传统比例减压阀，阶跃上升阶段时间缩短53.3%，下降阶段时间缩短85%；音圈式比例减压阀的频率特性也优于传统比例减压阀，其压力能够很好的跟随电流且在5 Hz以下的低频区相位滞后较不明显，而传统比例减压阀存在30°的滞后。音圈式比例减压阀可以提高车辆电液系统压力控制精度。

| Abstract: | The mathematical model of VCM is established. Combined with the experimental testing, characteristics of step response and frequency response are studied. The results show that step response of proportional pressure control valve drived by VCM is significantly faster than proportional pressure reducing valve. The time is reduced 53.3% in the rise phase, and 85% in the descent phase. The frequency characteristics are superior to proportional pressure reducing valve. The pressure can follow the current well, and the phase lag is less noticeable in the low frequency region below 5 Hz. However, proportional pressure reducing valve has a 30 ° phase lag. The proportional pressure control valve driven by a voice coil motor can improve the pressure control accuracy of the vehicular electro hydraulic system. |
