hey guys, i am trying to complete rolling element bearing vibration analysis in explicit dynamics, i have some questions for experts;

1) how to rotate the inner ring and the roller at the same time with presence of frictional contact between both component ?

2) from the 'Analysis Setting', it have 'remote displacement', what is the purpose of that option ?

Here i attached the image of the bearing

Hey Faez,

send .wbpz file then I can have a look and suggest you something if possible.

Hey Faez,

You don't have a cage to keep the rollers separated.

peteroznewman the model i get directly download fom SKF free CAD .. is that necessary to have that item ?

[FaezWahid95]

how can i get the .wbpz file ? need to convert or what ?? can you whatsapp me to go through detail about my project ?

Please use File > Archive to create a .wbpz file. That is how you share ANSYS models.

Hi Faez,

Do these changes and let me know the errors.

1. change the friction coefficient values to 0.1 to 0.2.

2. in connections select the whole circular surface of roller to the inner race and outer race.

3. remove the connections between side faces of the rollers and race.
