针对某型号发动机燃油调节器的脉宽调制（PWM）高速开关阀，通过建立高速开关阀系统动态数学模型，开展了高速开关阀调节工作过程动态压力与流量特性的仿真研究。对影响开关阀动态输出特性的相关因素进行了比较分析，结果表明：阀座通径、驱动频率与容腔体积等是影响高速开关阀动态性能的主要因素，并提出相应的改进措施。为改善高速开关阀动态调节特性、提高作动控制系统的控制精度与性能提供参考与借鉴。

For the pulse width modulation (PWM) high-speed on-offvalve of a certain ramjet reg- ulator, a simulation study on the system dynamic characteristics of pressure and flow rate during regu- lation of high-speed on-off valve was carried out by establishing a dynamic mathematical model of high-speed on-off valve system. The factors that influence the valve dynamic output characteristic were analyzed. The results indicate valve seat diameter, driving frequency and volume of control cavi- ty are the main reasons that influence valve performance. The methods to improve the dynamic per- formance were provided. A reference is also provided for improving control system accuracy and per- formance in this paper.
