Reply To: Tutorial or Help for 2 way FSI

Hello Paul,

That is how the BB works (just in case if there might be some misunderstanding). The Inner Race (IR) causes the Ball to move becuase of Frictional ocntact between them. The Outer Race (OR) are fixed to the Housing.

In order to reduce this friction, we provide Lubricant in these BB. So my work is to ASSUME that there is always Lubricant Film ( 1mm to 1 um range) between Ball and Races (IR & OR)..

You are right ---> ''I thought the ball does not rotate from mechanical contact with IR but that the fluid imparts a torque on the ball since there is a fluid film in between. ''

Force/Kinematics Transfer: IR - Lubricant - Ball - Lubricant - OR

In reality, the Mechanical objects makes the Fluid move. So Mechanical is the Driving Factor.

 

Most of the FSI (or which u also assuming here), Fluid is the Driving Factor ..(like water flowing in the pipe).

So is it possible in Ansys FSI to mechanically move the objects --> causing fluid to move. This means the contact zone are always changing. 

What should I do so as to replicate this animation in Ansys FSI??

 

I guess the Ball is receiving the Forces....
