how to create tension beams (steel cable) in simulate

Hallo Creo Simulate community

I am working on a frame construction and would like to do some mechanical simulations with this frame. The simple construction is a 3D Frame with cable elements (can only carry tension).

Can anybody help me? How one has to define a "tension only beam" in Creo Simulate?

Thank you for your support

Otto

Hello Otto,.

Do you have a plan or an image join us?

Kind regards.

...especially it is a frame construction for a photovoltaic cell. The construction itself is not so important . It is learning stuff...

But with designes like this I am learning to handle Creo Simulate.

Mainly it is a frame made of tubes (33 mm outer diameter and a wall thickness of 2 mm). To improve the stability I added some robes (cables) to avoid a collapse.

Can you provide some specifics on what type of analysis you want to do and the goals of it? Generally speaking, Simulate does not have a "tension only beam". However, depending on the conditions of the analysis, you might be able to use a pre-loaded beam element (which will work with any linear analysis) or a deflection-dependent spring element (which will only work in a non-linear analysis).

...currently I am designing a 3D frame for a photovoltaic cell which should be mountet on a sailing boot (private stuff). During the design interations I had the idea to start some beam FEA studies to see the stability of the design and to learn how to use Creo Simulate.

The current design of the frame has cables to increase the stability (cables are used to have less welding conections as well as a nice appearance).

Aim of the simulation is to assess the forces and mechanical loads on the tubes and cables as well as the see the deformation of the frame under load. To be honest it is not really critical but I started and now I would like to finish this task and learn....

thank you otto

Hi Paul.

Why did you create a rigid link between Beam1 and Beam2 (and also Beam1 and Beam3)?

Why not just simply connect the beams together? See the picture below.

I tested it without Rigid link and the results are pretty much the same.
