Pressure Gauge Analysis: static deformation + mechanism simulation?

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!
