摘要
曲线拟合法在发动机的故障诊断中可以用以判断发动机的故障类型,本文通过计算时域及频域中工程机械发动机工作时的拟合曲线与标准拟合曲线之间的距离,对发动机进行故障类型判断,通过计算,得出计算结果判定的故障类型与设定故障一致的结论。
In the engine fault diagnosis, the curve fitting method can be used to judge the types of fault, By calculating the distance between the engine at work and the standard curve fitting in time - domain and frequency domain to judge the type of fault, through calculation, it is concluded that the calculation result is consistent with the types of setting fault.
