vibratory stress relieving equipment，How to judge the result:

vibratory stress relieving equipment

One of them happens as follows,means good result:

a: Amplitude Time (a-t) curve flattened after rising.

b: Amplitude Time (a-t) curve rise and fall and then flattens.

c: amplitude frequency (a-f) curve ,the peak of after vibration is higher than before.

d: amplitude frequency (a-f) curve ,the peak of after vibration is left before.

e: amplitude frequency (a-f)curve,the bandwidth of after vibration is narrower than before.

Screen shows three results:

For the result,there are three results will be showed on the screen:

1,"ok" means result is good,it's effective;

2,"error" means result isn't good,need vibrate again;

3,no show means the vibration is invalid,we should adjust the vibrator,sensor,pad or eccentric;

if you vibrate the same frame for many times and the result always ok,it is normal,

and the vibrating time maybe will be shorter and shorter,as the residual stress was relieved completely.
