    Fourier Series

    Hi Greg - I've done all the math (I think) but i still don't see how am i may going to graph it. Please help See attached file. Thanks a lot. Thomas http://files.engineering.com/getfile.aspx?folder=91ab00ec-41c0-4be3-a1f1-b3f8c7c2fddb&file=Wheel_runout.xls

    Non-linear FEA

    Wow! I've been working at this wheel company for x number of years and we've never done a correlation yet; although, we correlated our stress values and distribution vs. actual performance test by just comparing FEA results to pass no-pass performance lab reports. I’m sure we will pull out the...

    Non-linear FEA

    Hi Guys - Is any body doing non-linear simulation on wheels yet? This will be for the impact. Thanks!

    Wheel Balance

    Thank you guys! Here is my problem, I'm working on a wheel that will be fitted with a presure sensor on the drop-well area, and after the part is fitted with it the balance goes up. So, I'm thinking about a counter-weight at specififed radius. With the explanation you guys have given me, now...

    Wheel Balance

    Hi Greg -did that. but the amount was too large. e.g. mass of the part 18.4 kg C.G. X=57.93mm Y= 0.227mm Z=-0.019mm Geometrical axis is "x", which is going thru the pilot bore. Radius of C.G.=0.228 Static unblance= 4.19kg-mm Is this correct? Now, I want correlate this with a...
