摘要
在周期性的内燃机曲轴瞬时转速实测信号中常会出现许多畸点。为滤除畸点 ,一般采用低通滤波的方法。但低通滤波法有其局限和不足之处 ,为此 。
A 1ot of distorted points often appear in periodic crankshaft instantaneous rotation speed signals.The common method to filter the distorted points is the low pass filtering method,but it has some disadvantages and localization. Therefore, the method, which can attenuate distorted points fast without any new errors, is presented.
