摘要
本文针对某涡喷发动机燃油压力高频脉动现象,建立了供油调节系统的动态非线性数学模型,并用全局分段线性化方法进行了稳定性分析,确认燃油压力高频脉动是由于系统不稳定造成的。
A dynamic nonlinear mathematics model of fuel system was set up for the high-frequency pulsation of fuel pressure in a turbo jet.The stability of the system was analyzed with whole-scale-subsection linearization.It was confirmed that high-frequency pulsation was caused by the instability of the system.An improvement method was proposed on the basis of the analysis of the relation between system parameters and system stability.
