Attached is the mech data if anyone wants to run the problem. It seems if I apply frictional contact it will get the correct answer, but this shouldn't be required because I'm technically applying friction numbers until I get the right results which is wrong...
I have attached a side by side screenshot of a problem I set up just to learn how to use explicit dynamics.
My problem is doing the problem in 2D and 3D. The 3D results seem to follow real world results. The 2D problem doesn't deform the same and the results differ. I applied a Axisymmetric...
I've been using ANSYS for a few months now. Recently, I have been trying to control the shape of my elements like FEMAP, but it doesn't seem like you can in Workbench.
I want to recreate this mesh on a 0.5 X 5.0 member.
Are there any easy ways of doing this? Thank you in advance...
I have attached a screenshot of where I am stuck.

okay, i managed to figure out how to change the orientation of the beams. My other problem is when I try to run my analysis, it seems like all the bodies are separated. Do I have to put them in contact some how?
Fantastic! That actually worked! Now my last question, how do I change the orientations of the beam? I can see their vectors coming out, and some of them are facing the wrong way. Thanks so much Orel!
Hey Everyone,
I am new to ANSYS and I don't have a clue on how to do the following:
1. How do I apply different profiles to different line members? Ansys for some reason applies one profile to every sketch visible, even if I have different sketches for different lines.
2. How do I change the...
We have a flight simulator built out of an old helicopter. There are two air vents, both 1.5" in diameter. We want to connect a blower to the helicopters ducts to supply air to the pilot and co-pilot students. My question is:
1. What is a comfortable amount of air that can be blown on the...
Just wanted to update everyone. Here's how my fixture turned out. Very rigid and strong. My friend gave us a good quote to just get the whole thing CNC.

For the stress test, I think I'll run an analysis if my Solidworks at home has shock and vibration.
I've looked over a lot of fixtures from this site that seem to be welded.

Attached is a 3D PDF file of the fixture I have decided on. It is a 3/8 THK plate and I am thinking of welding the bottom ribs all around. The holes will have Helicoils inserted in all of them due to our constant mounting and unmounting.
My concerns are:
1. Will so much heat being applied...
Use, you are correct. THe R2 unit is the shaker itself and the cube + plate are the fixture.
We are not going to test the units packaged but rather mount the unit itself onto the table.
Would it be a bad idea to cut down the cubic looking fixture to lose some weight and add on a larger table...
Here is the old fixture. They nicknamed it an R2 unit for a reason ^_^.
The fixture is quite heavy and is definitely made out of stainless steel from what I can see.http://files.engineering.com/getfile.aspx?folder=22eb7661-33ce-42e9-9f5c-6a342b83219f&file=DSC_0486.jpg
Thanks guys,
I will attach an image of the system as well as the old fixture that was on there. It is only a sinusoidal controller (I know, our company is kind of small....) and a very old system from LSD.
This system was originally used at a auto parts manufacturer company.

We plan on mounting the vibration table onto isolation pads. Any advice on how to design this vibration fixture? I see a lot of pictures of tables with an array of threaded holes. I assume that mounts are fastened into these threaded holes am I correct?
I heard that making the fixture out of...
Good morning everyone,
I have been tasked to design a fixture that will be mounting our display units to our vibration system. We want to simulate the vibrations that our units will go through when shipped.
I've never designed a fixture before. Does anyone have any kind of advice or articles I...
I actually worked at AeroVrionment for 6 months on a contract. I quit because they don't hire directly. They keep you as a contract emplyoee for up for 1 or 2 years sometimes with no benefits or vacation. I took my current job because I needed benefits and vacation. But other than the business...
