FEM of crankshaft with rolling elemnt bearings
FEM of crankshaft with rolling elemnt bearings
(OP)
Dear All
I am attempting FEM of a compressor crankshaft having ball bearings as main bearings.
Can some body help me in modelling the bearing?
What constraints are to be used for ball bearings (e.g. all dispacements blocked, all rotations are blocked ?)
I would be grateful if somebody can cite a paper or book reference as well

A good way to model radial bearings may be to fix radial movement and allow tangential and axial movement. This means assigning infinite stiffness to the bearing supports.
