摘要
本文对发动机台架试验数据进行曲面拟合，建立发动机供油拉杆不同位置时速度特性的数学模型．根据该模型，实测发动机转速和供油拉杆位移，得出实际工作过程中发动机的输出转矩和功率．
The paper establishes a mathematic model of speed performance of engine with fuel control rack in different positions. By measuring the rotation rate of the engiue and diplacement of the fuel control rack according to this model, we can obtain the output torgue and power of the engine in actual working.
