Vibration performance of coventional lock washers

[Tunalover]

Does anyone out there have test data showing the vibration performance of bolted joints with conventional (toothed e.g MS35333-X and helical-split e.g MS35338-X) lock washers as compared to the same joints without lockwashers? I'm trying to make a case for elimininating the lock washers but can't seem to get my hands on any hard facts; all I have to go on is educated opinions...

Thanks!

I have no data, but we always used the toothed washers when viberation was a concern.

Good luck.
