Contact analysis in Flexible gear

AI Thread Summary
The discussion focuses on a contact analysis model of a flexible gear in ANSYS Workbench, comprising a flexible gear (FG), wave generator (WG), and rigid gear (RG). The model simulates the deformation of FG from a circular to an elliptical shape under force from WG, allowing FG to engage with RG for torque transfer. The user encounters issues with obtaining suitable results, particularly with non-linear contact conditions and meshing quality. An error message appears during the solving process, indicating potential problems with the setup. Assistance is sought to resolve these issues and clarify what constitutes acceptable results for the model.

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.

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
