I'm currently working on a project to model a pressure gauge
and I'm stuck on the simulation. For those who don't know how a
pressure gauge works, you pressurize a curved, elliptical
cross-sectioned Bourdon tube resulting in the tube trying to
straighten itself. The straightening tip of the tube is attached to
linkages which moves gears and what not in the mechanism to cause
the gauge pointer to rotate as the pressure increases/decreases.
I've gotten successful models of the pressure deflecting the Bourdon tube tip but it doesn't seem like CosmosWorks alone can succeed in what I'm looking for. Is there any way of using CosmosWorks or perhaps CosmosMotion as well to get the simulation I need?
Thanks in advance!

I'd highly recommend that you use the Nonlinear study in CW Advanced Pro for the tube analysis for 2 reasons. First, the large displacements you are going to have may not solve (or solve with sufficient robustness) in a Static study, even with Large Displacement turned on. Second, the response as the pressure increases is probably not linear, in path or magnitude of deflection vs. pressure. You'll need N/L to track the actual tip deflection vs. pressure.
Good luck!!!! When you nail this one, please consider presenting it as a case study at a local SolidWorks or COSMOS User Group!!!
