simulation fem motor shaft

[Mat_94]

Good evening to all, I am a university student of mechanical engineering.
as part of a project I must carry out a fem analysis on a small motor shaft (diameter 8 mm).
I wanted to know what the correct constraints are to be applied for static analysis.
in fact I tried to bind the tree in various ways but all the results are not in accordance with the sizing of the tree from us made that we believe correct.
Thank you.

how is the piece actually bound?
where and how do you receive loads?
answering these questions you will already have the answer you are looking for. There is no unique method that goes well for example for all trees.
for each case to be analyzed you will have to consider how the structure actually behaves and act accordingly.

in reality it is connected with a rigid coupling to the motor and with a tab to the wheel. We also provided two radial bearings to bear the load from direct force only perpendicular to the shaft axis.
thanks to the attention; )
