gotcha, I went to the bolt pretention and for step 2 selected lock in the left hand table in the 'define by' options.
I'll do them all now and re run the simulation.
Thanks for your help!
I dont seem to have lock, screen shot added of the options I have.http://files.engineering.com/getfile.aspx?folder=eab94bd2-4d46-4810-bd85-41e1eb1242d5&file=image_2.JPG
There are two other loads on the top plate.
I run the simulation with all the loads and the bolt pretentions applied.
What do you mean by loadstep? I'm quite new to ansys having only used Cosmos before.
There are three parts in the assembly plus the bolt. I put split faces on the bolt shank to add the contacts too. This was done as I was having initial problems of parts penetrating through each other.
The bottom block (which in real life the bolt screws into) has a hole in it the same diameter...
I think your right, but shouldnt the entire model deform in a proportional manner even if it is scaled up? why this thin walled cyclinder appears looks a bit odd and the part would never deform in this way under load even in a much reduced scale....maybe?
Morning all,
I am working on a static analysis in Ansys and have included the models of the screws so I can add pretension.
At first I added the pretension to an outer face on the screw shank. (the screw has multiple split faces on as the screw bolts 3 plates together)
Running the analysis...
Hi,
I have performed a random vibration study using cosmos advanced professional and obtained rms values for stress, displacement and acceleration. Is it possible to progress this study into a fatigue life analysis to find out if the part being analysed will survive the random vibration over a...
Hi
Can anyone help with the following NACA airfoils:
NACA 0008-1.1-25
NACA 0005-.825-50
I am trying to find out what the numbers following the first four digits represent.
Thanks
Mike
