Hi All,
I want to simulate a coil with a force applied to the inside pushing out on the coil-ie in the radial direction. I think that the correct fixture is "On Cylindrical Faces" using the face highlighted and with "Radial" selected under Translations. Unfortunately I get the error "Excessive displacements were calculated in the model". Any help? I got it working with a cylinder but not with the coil. Also, I understand that the radial box (under Translations) will allow the coil to expand radially, but I'm not sure why you need to enter a value? It doesn't seem to work whichever value I choose.
Thank you!
Nicholas,
I'm not very familiar with SolidWorks Simulation, but it seems like you are trying to enforce a specified radial expansion on your coil is that correct?
Did you actually slice off part of your coil to get the cylindrical face? If you did slice it, the lost material may have an effect on your results.If you just did a split line, then perhaps the face not really being cylindrical is causing a problem.
Are you actually simulating what happens when the coil is placed over a mandrel of some sort? In that case, I would actually use a tapered mandrel to enforce the expansion.
