摘要
对某小型重油发动机电喷系统内部的高速电磁阀,进行了建模仿真与响应分析。先建立该高速电磁阀的数学模型,再用Matlab/Simulink对其仿真。通过对不同输入参数的仿真对比,分析影响电磁阀响应的主要因素,从而确定模型的各项参数,得到该电磁阀的稳定及快速响应。该仿真模型考虑了铁磁材料的磁阻及磁阻变化对电磁力的影响,对电磁阀的开发和研制具有一定的参考价值。
The response of the high-speed solenoid valve,which is inside the EUI for a small heavy-fuel engine,is analyzed.The corresponding mathematical model is set up based on the circuit equation,the magnetic circuit equation and the dynamic equation.It is simulated by means of the SIMULINK tools in MATLAB environment.By comparing different results simulated in variable parameters and analyzing the main factors affecting the dynamic response,the final parameters are determined,even the stability and rapid response of the solenoid are gained.The simulation model which is considered the reluctance change of the core material is valuable for further research and development of the solenoid valve.
