摘　　要：燃油系统作为飞机配电系统的重要负栽,地位特殊,作用重大。分析了飞机燃油系统的工作原理,运用键合图技术对该系统的主要用电器件燃油泵进行建模,通过Saber软件中的TLU(table look-up)方法构造了该泵的可视化仿真模型,继而在Saber Sketch中模拟某飞机燃油系统,分析相关参数变化对飞机配电电网的影响,仿真结果和实验数据基本吻合。The effect of analyzing the electrical plunger pump of airplane which is one of the most important loads, is very significant. The operating principle of electrical plunger pump of airplane is analyzed. In this foundation, a nonlinear mathematical model of piston pumps is set up by the bond graph modeling. The Mathematical simulation software called ＇ Saber＇ is used, and the model of oil pump is visually simulated by putting up external characteristic curve. Then the aircraft fuel system is simulated in Saber Sketch. Simultaneously, the influence which is caused by correlation parameters is studied and the results are accordant with experimental data.
