Catia Analysis and simulation

Catia Analysis and simulation

Catia Analysis and simulation

(OP)
Hi everyone,

I'm new on that so I'll try to explain my self properly hehe.

I'm triying to do some finite element analysi withe the modul Analysis & Simulation of Catia V5-16.

The problem comes around when I try to define the loads on my figure. I'm working with an endlees worm and I have to apply the loads not in the whole perimeter but in a small surface, the one in contact with the gear. How can I define this surface? I have try to project a plane on the worm but it doesn't work properly.

I have the same problem when trying to analyze a spindle, as I do have to apply the loads only in just a pair of the threads and I don´t know how to do that. I have read something about the extract modul but nothing especific neither good explained.

Thanks everyone!!

RE: Catia Analysis and simulation

Hi,

The easiest way I see is to go in shape generative module, extract the the whole surface to create a matching 2d surface. Then with planes, lines or whatever you need to, modified that 2D surface to get the exact surface you want ton apply the load on.

Then, go back to Mechanical Design - Part Design and find the icon for Sew Surface (usually hidden below Thick surface definition icon, by default). Then select your surface and uncheck simplify geometry.

There you go, you should have a surface defined on your part and you can applied loads or constraints on it.

Hope this helps.
