摘　　要：利用磁流变流体的磁流变特性设计了磁流变数字阀,给出了磁流变数字阀的结构和数学模型,根据所设计数字阀的工作状态,提出采用脉宽调制(PWM)方式实现对数字阀的压力、流量控制,并进行了仿真分析。分析结果表明:磁流变数字阀具有良好的静动态特性、较高的切换速度和响应频率,易于实现智能控制。Magnetorheological digital valve was designed according to MRF magnetorheological characteristics. The magnetorheological digital valve structure and mathematical model were given. Aiming at the designed magnetorheological digital valve working con- dition, pulse width modulation （PWM） was proposed to realize the pressure and flow control. Magnetorheological digital valve was investigated by AMESim. Simulation analyses show that the magnetorheological digital flow control valve has good static performance, high switching speed and response frequency, easy to realize intelligent control.
