vibration on bearing cage
(OP)
? try to analyse the vibration effects on bearing cage,
under the vibration the cage fails after some time,(i think because of fatique=
does anybody recomend me a source to understand what happens on yhe cage?
and which fea prog. do you recomen to analyse this?

RE: vibration on bearing cage
Did you have a metallurgical analysis performed to identify the material and cause of failure? Typically vibration causes brinnelling of the rollers and races as experienced by Chevrolet in shipping Vegas in the late 70's. Do you have additional informatin such as conditions, time, environment, etc?
The cage just goes around with the rolling elements and keeps them separated. Ir sees virtually no load.

i think the vibration on the cage depends on the angular velocity..
and if i give an angular acceleration to the or approximately 160 G force occurs on the ball..(so the cage)
i think the failure of the cage depends on vibrational fatique..
what is your opinion?

the cage made of steel and it fails from the rivet holes or the radiuses where the ball pocket starts..
what kind of computer prog. did you mention?
is there a spesific program about these problem?

Excessive speed for the bearing can do that, as well as outright lube problems.
If the balls are trying hard to change lanes the cage suffers badly. Excessive thrust loads or bad bearing seat geometry can do that. Mechanically it has to be right. I'd say more bearing (and vibration) problems are solved with a dial indicator than FEA.
