FEA tip

Good afternoon,

 

I need yours suggest for this problem.

 

I have a plate bolted to a shaft with a nodal force perpendicular to shaft.

 

I would see what’s the strain result on the plate due to the shaft connection.

 

My FEA idea to analyse  this parts is that I change the contact surface of the two elements in welded contact, I mesh with a brick elements, I applied the force and I constrain the shaft and the plate hole, with a fix constrain ( to simulate the bolted connection ).

In your opinion is the right way??Is it better to build a bolted in Algor???

 

Thank you in advance

 

Best regards

 

Manuel

Hi Manual,

 

I suggest that you attach an image of the model. Be sure to mark it up with any additional explanation. This will help everyone to better understand the arrangement.

 

You mentioned about using constraints (boundary conditions for us older timers 😉 instead of a bolt. This would be acceptable only if in real life the bolt connects the plate part to something that is stationary, and that something is not included in the simulation. If in real life the bolt connects two pieces, both of which are included in the simulation, then you cannot use constraints.

Here there are the imagines and the additionaly  explanation. Sorry for use Constraints instead of boundary conditions 😄

 

Thanks
