Contact analysis in Flexible gear

Click For Summary
SUMMARY

The forum discussion focuses on the challenges of analyzing a flexible gear (FG) model in ANSYS Workbench, which includes components such as a wave generator (WG) and a rigid gear (RG). The user is attempting to simulate the deformation of the FG from a circular to an elliptical shape under applied forces, specifically using frictional contact types between FG and WG or RG. The model fails to produce suitable results, particularly when setting non-linear contact conditions with medium meshing quality, leading to error messages during the simulation process.

PREREQUISITES
  • ANSYS Workbench familiarity
  • Understanding of contact mechanics in simulations

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.
