Re: Bike frame, FEA, Creo 2.0
If you're after frame stress then I would build it with rigid shock absorbers. To be honest, unless you have a good reason I would analyse just the frame component, applying calculated loads at all the...

Hallo Denis, thank you. You mean that if the light is yellow the calculations could be imprecise? if yes, therefore that would be a (very) bad surprise....even worse if it could not be changed so...

Did you mesh with shells or with solid elements? Have you tried to model a rotating contact like this in a smaller model, to see if it works?

Mixed mesh is not a problem, as long as it is set up properly. To expedite your studies, I would recomend running quick checks until you get the model to behave properly, then run a convergence analysis.

Re: Bike frame, FEA, Creo 2.0
Quick Check isn’t a convergence method since the model is run only for a single fixed (low) polynomial order (shown below p3-p3). The stress results should never be trusted. What a Quick Check is...

I managed to get results with solids onlyI used rigid link for the shock pins. Bottom bracket and head tube are fixed. Which isnt right as the bottom tube takes almost no load. Rear axis takes...

As far as I know you can use Inertia Relief always. All it does is balance out the forces on your model with some inertia spread over the whole model. That way you can for instance apply only loads and...

Re: Can you change the iteration time step in Creo Mechanism?
I mean when the analysis is running it's choosing a time step to measure a measure like position for example. I think Mechanisms uses a fourth order Runge-Kutta to solve the equations of motion of...
