摘要
针对某型航空发动机燃油调节器常见的大幅跳变和平衡占空比失稳问题,通过对油路缓冲器、控制腔、占空比活门和高速电磁阀等关键组件的流量平衡分析,确定了占空比与高速电磁阀额定流量的定量关系,发现占空比变化平稳性和占空比活门的灵敏性2个燃油调节器性能指标的矛盾关系,建立了影响占空比稳定性的多目标性能函数,提出一种基于多目标优化的占空比活门流通面积和高速电磁阀额定流量参数匹配方法以获得最佳参数匹配。仿真结果表明,本文优化后的参数匹配结果与基于专家经验的匹配结果相符,这为对该型燃油调节器的正向设计提供一种科学的方法。
Aiming at the vibration problem of the metering needle and the issue of the instable fault of the duty ratio of the High-speed Solenoid valve,this paper builds the quantitative relation of the stability of the duty ratio with respect to the area of the duty cycle valve and the normal rate of flow of the high-speed solenoid valve by analyzing the rates of flow of the fuel buffer,the control cavity and the duty cycle valve,and find that the sensitivity of the duty cycle valve and the stability of the duty ratio are conflict,such that two objective functions of the performance indices of the regulator are constructed,and a multi-objective optimization based parameter-matching method is proposed to obtain the optimal parameter match.The simulation results indicate that the parameters obtained by the proposed method agree with the parameters obtained by the expert experience,which provides a new method for the fuel regulator design in the future.
