Two words: stress concentration

Re: Wheel contest
 

Wheels that don't break were never part of the contest....I would have to analyze these before I built them (I probably wouldn't) but i still think they look pretty.:D

Sorry - guess I shoulda read the rule before posting!

OK, so here's my "keep it stone-age, stupid" entry:



Six of these babies should solve a lot of toppling bot problems!

Re: Wheel contest
 

What program did you use for the stress calculations? Thats kinda useful.

Re: Wheel contest
 

Sorry - I just linked a picture from Google for an engineering company's site. I can't claim to be an expert in the stess analysis field - I just play one on TV, er CD, er - okay, so call me a poser!

Re: Wheel contest
 

Inventor 10 and up does stress analysis.

Re: Wheel contest
 

does is a relative word....if you are going to use any FEA software please understand that there is more to it then clicking "analyze" and getting the answer. You must understand mesh size, load positioning, load types, etc. FEA can be great but it can also give you a false sense of security...kinda like a radar detector; it will detect a police officers but won't tell you where they are.

Re: Wheel contest
 

If one understands mesh, load positioning, etc. (which I don't :) ) can Inventor's stress analysis feature be used to get accurate results?

Re: Wheel contest
 

I needed something stronger than our typical omniwheels because they'll be cantilevered and exposed in the design I'm working with now.


There's no reason wheels can't show a bit of team spirit :)

Re: Wheel contest
 

I never got Inventors stress analysis to work quite right. I prefer CosmosWorks (a plugin for Solid Works). Inventor will output to ANSYS, though. That probably wont be much help to you now, but maybe when you go to college and there's network licenses :)
