应用频域数字滤波消除弯矩对发动机输出轴转矩测量影响的方法

A Method on Detaching Torqure from the Measure Signal of Engines Output Axis by Digital Filter in Frequency Domain

测量发动机输出轴的转矩，会受到输出轴上弯矩的影响而产生测量误差。应用频域数字滤波可消除弯矩影响而精确测量出发动机输出轴的转矩．

When the torqure of engine's output axis was measured, the measure signal involvedinfluence of the flection moment of the axis.This paper discussed the method on detaching torgure form the measure signal of the axis by digital filter in frequency domain .
