SW simulation beam configuration

Simulation Generality
1

Hello

 

I am currently doing a simulation under SW2014 simulation and I am having a problem on the beams.

 

Let me explain, on my mechanically welded frame I have 2 beams that meet (see doc 1 in PJ) with in the center of one of the beams a lifting ear.

 

When I do my simulation, solidworks makes the 2 beams join in their center which makes one of the beams go through my lifting ear and therefore gives me false results (see doc 1 in attachment).

 

Is there an adjustment or configuration to be made so that the 2 beams are simulated as what is built in reality?

 

Thank you

Hello

 

With a wired model, I don't think we can do better. The beam elements must necessarily meet at the intersection of their neutral fiber to be considered bound.

For a more realistic modeling in this area, a surface representation would certainly be more suitable.

Totally agree with our friend @ Chamade

 

I understand that it is preferable to do a surface model in many cases

Ok, thank you for your answers.

 

The problem is that I'm not an expert in surfacics.

 

What should I do in the surface area? The lifting ear?

 

And then I could always do a simulation on the lifting ear?

The idea is above all to represent the tubes in the surface. That way, you can represent the junction more realistically.

To avoid overstress at the junction, go directly on square sections (forget the rounded corners of the tubes). Also be careful to check the position of the shell elements in relation to the surface (= if you represent the outer surface, the thickness must be on the inside side of the surface and not on each side).

Model the ear in surface, why not. On the other hand, as you put the effort into the piercing, I don't know how he will manage it.
