Need help with wheels design (Yamaha R1)

[salavat]

I have an opportunity to make build-to-order forged aluminuim wheels for R1 (2003) at quite a reasonable cost, but have no idea how and where to get technical design for wheels with dimensions, whether to take off wheels from the bike and scan them somehow. Anyone has any idea?

Thanks in advance,

Perhaps I am misunderstanding your post, but if not, you might as well state you have an opportunity to perform cheap brain surgery, but you have no idea where to obtain cranial anatomical knowledge or information on how to surgically expose the brain correctly and reversibly.

Being an engineer myself, working for the largest automobile manufacturer in the world and having considerable design experience under my belt... I'm going to take a stab at answering this....

IF the opportunity you have is legit, you are going to need an avalanche worth of resources to pull this off AT ALL.

Reasons being as such:

1. Design of mechanical parts of this significance REQUIRE an engineering degree [in addition to several years of related experience], usually MSE level or above.

2. Design software AND required supporting hardware for the ACTUAL 3D design... examples of such applications are: Unigraphics ($50k for software + $30k for hardware, etc.), ProE, CATIA, etc.

(the reason you need this software is to not violate any of the "natural" laws of physics in the design... cross-sectional area, material strengths under multiple types of loads and velocities... basically: high-end FEA analysis. FEA stands for Finite Element Analysis... as well as half-a-dozen other types of "theoretical" analysis) [failure to do this will result in almost definite failure of the design]

3. Without reasonable understanding of the required symmetry of the design, both radially and longitudinally... any type of design that doesn't take certain parameters into consideration will ultimately lead to the rotation of the wheel being off balance [or even worse, developing resonating oscillations at higher rpm's] that would lead inevitably to the wheel's total disintegration and probably death for the rider... We view this in the engineering community as a career limiting move.... [anyone remember the video clip of the suspension bridge in San Fran that had the 1940's car on it as it bounced back and forth 50+ feet???]......

getting the picture yet??

I'm not saying this isn't a good idea... I'm just saying, if you are going to tackle something of this magnitude... do it right... GET THE RIGHT PEOPLE TO HELP YOU.



have a great day....

ps - as far as "scanning" a rim.. you're talking about stereolithography and yes, it does exist... not for ACTUAL design for this application though.... [also, very $$$$$$$$$$$$$$]

pss - if you are still going to do this call me and I'll give you what I think is the best approach ph: 812.219.8000
