摘　　要：根据呼吸器减压阀传递函数模型,利用Matlab软件对减压阀整个工作过程进行了数值仿真,运用最大超调量、上升时间和调节时间3个时域指标判定减压阀响应特性,得到了单一结构参数和工作参数对减压阀出口压力动态响应曲线,为减压阀的设计提供了参考依据。Based on transfer function model of reducing valve for oxygen breathing apparatus, numerical simulation was done with Matlab software, determined decompression time domain response with three indicators such as maximum overshoot,rise time and settling time,Obtained Outlet pressure dynamic response curves of single structure parameters and operating parameters ,that provide a reference for the valve design.
