Overview
The aging processing time of the vibration aging instrument is 10-40 minutes. The vibration aging process adopts the resonance principle: the $r $n vibration aging equipment uses high-frequency vibration to eliminate stress. High frequency vibration, through a certain frequency and periodic regularity, promotes the displacement of residual stress crystals inside the workpiece, reducing the stress at the high point and lowering the overall stress to the stress equilibrium point.

The aging treatment time of the vibration aging instrument is 10-40 minutes
Due to the different structures and weights of various components, the magnitude and distribution of residual stresses are also different, and the vibration time selected for vibration aging is also different. Through extensive experiments, it has been proven that vibration eliminates residual stresses mostly in the early stages5Completed within minutes,5The treatment effect after minutes is no longer significant, so we generally choose the appropriate vibration aging time according to the principles specified in the table below:

1How to determine whether the timeliness effect of the parts meets the timeliness requirements?
pressJB/T5926—2005When one of the following situations occurs, it can be determined that the vibration aging process effect has been achieved according to the standard (Machinery Industry Standard of the People's Republic of China).
a.Amplitude time（a—t）The curve rises and then flattens;
b.Amplitude time（a—t）The curve rises, then falls, and finally flattens;
c.Amplitude frequency（a—n）The peak acceleration after curve oscillation increases compared to before oscillation;
d.Amplitude frequency（a—n）The resonance frequency of the curve after vibration decreases compared to before vibration;
e.Amplitude frequency（a—n）The bandwidth of the curve after vibration becomes narrower than before vibration;
fAmplitude frequency（a—n）The resonance peak of the curve exhibits fission phenomenon.
