Contact analysis in Flexible gear

[virgo86]

Hi everybody,
I'm working on an analysis model of flexible gear in ANSYS workbench.

This model has 3 components: flexible gear(FG), wave generator(WG) and rigid gear(RG)

Applied force have two case: WG makes FG deforming from circular shape to ellipse shape, the FG contacts and engages to RG for transferring torque or moment.

I used all contact type is frictional. Contact: FG, targets: WG or RG.

The specicial of this model is that FG and RG are not contact together in first time. After being deformation, FG can be connect to RG.

I try to solve model, but model didn't give me a stuitable results.

I wish that I have some help for my trouble!

Explain what you believe should be a suitable result as compared that the one shown.

I try to set some non-linear condition for contact condition with medium meshing quality. And program shows me a error message.
