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 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
