Hi,
I have designed a part that I wish to manufacture with a special material. But before doing so, I would like to see if the part is going to sag under its own weight.
The part is mostly 3 tubes of different bore-section stacked together.
I thought I would be able to study this in simulation express, but I did not find how.
Could anyone help me with this ?
Thank you !
In "big boy" FEA, this is done by applying acceleration equal to gravity. SW's Express does not allow this.
If your part is uniform enough, you could approximate with a directional load distributed across upward-facing surfaces.
I tried this at first, but the part was deforming so widely, that I thought there must be an error.
I will give it a second look. Thank you for your help.
You're stuck with forcs and pressures in simxpress. Roland's workaround might work. Might want to apply it along the center/cog.
If you need this analysis run for you, we provide that service at hawk ridge systems. Just email me at jared@hawkridgesys.com.
Thank you for your suggestion. I will contact you if I go nowhere with the simxpress simulation.
Just wanted to give some update : I used the simulation premium package to simulate my part (my institution has a few licenses you can borrow). I am glad I did : the sag is so terrible I don't even want to belive it is !
So now I am off to change my design and manufacture my part in a different way ;-)
