摘要
为了对电磁驱动燃气阀的动态响应特性问题进行研究,建立了燃气阀的非线性数学模型,研究了不同阀门参数对燃气阀开-关过程各阶段响应时间的影响规律,并利用Matlab/Simulink平台的电磁、机械和气动耦合的一体化仿真框图,进行了燃气阀动态过程仿真。仿真结果表明:分阶段响应时间分析方法为阀门响应特性研究提供了新的思路;驱动电压、预紧力、线圈电阻和匝数是影响响应时间的重要因素;阀门参数变化对各响应时间影响程度不同,对总响应时间to、tc的作用效果相反;响应时间tt1、t't1数值较小,且基本保持不变。
In order to investigate dynamic response characteristics of electromagnetic gas valve, the nonlinear mathematical model and electromagnetic, a mechanical and pneumatic coupling integration simulation diagram based on Matlab/Simulink software was presented. The dynamic response characteristics of gas valve were simulated, and the influences of different valve parameters on response time at each stage of on-off process were analyzed. The re- suits show that, the segmentation research methods of response time provide new ideas for response characteristics re- search of gas valve. The voltage, the pre-tightening force, the resistance and the number of winding circle have important influences on response time. The influences of valve parameters are different on each response time, and op- posite on overall response time to and tc. Response time tt1 and ttl are short, and keep constant basically.
