    It's Sprocket Science

    One or both sprockets may be incompatible with your chain link length or roller dimensions.
  2. Gimme relief

    So, if you are 'designing' your 'engine', design it with the proper clearances for the optimized oil viscosity and warm to hot temperature and expected rpm band and omit a pressure relief system....
  3. Track Race

    Just to clarify: THIS is a racetrack. Notice the steel and concrete retainers ? The best path thru this maize is the science project, not like a single track1285 copied from a golf cart going 6 -...
  4. InFarted Track Map

    Z: It was the only way I could get you to bite on the total concept at hand from an unblemished, unMatlabed and unOptimumed podium. No need for gpxread, just a couple of moving median filters. Who...
  5. Recommended Lapidary Method Discussion

    Here is an excellent paper by Honda on the subject of Lap Time Simulation. (Speaking of which by the O.P.) Go 4 it. Log-in to download and study.

    OK, so what does Tesla use for setting tire and vehicle parameter specifications and submissions ? Is there actually a 'Tire & Wheel Release Group' empowered to analyze/synthesize, specify,...
  8. Off Track Betting

    Am I missing something ? A race track has finite width lanes for which you shoehorn the car thru a racing line path. This 'line' will be different for each of vehicle and tire parameter settings.

  9. Tracking Curvaciousness

    But wait, curvature is just the inverse of the track radius at each section. It takes 3 points to define a circle which they would lie on, and so
    all you need to do is traipse thru the track data...

    Neurotic Analyzer

    Fine. But what does an ANN or an RNN bring to the table (read that STUDENT'S table) other than a model of the data ? Really, you want a model of the TIRE which was tested and have obtained a bag of...

    Who gives a Hz. ?

    Why don't you try to explain why you think you would need to know this frequency? Are you going to design a motor, modify a valve train, or make a wind chime from camshafts?

    Otherwise, take on a...

    OK, so you have preliminary results for tire model functions. Analyze them with a vehicle dynamics simulation and evaluate their capability and suitability. FSAE car's are not that complicated...

    May I have the Envelope, Please ? And the Winner for the FSAE Best Tire Award is Clea

    Put the Pressure on

    Is that with the pump motored or with an auxillary hydraulic supply plumbed in ? Otherwise, that's normal for the range of T-bar windup in the valve body. You would be twisting the T-bar up against...

    BTW: My admittedly scant search of Round 1 thru 7 tire files seems to indicate that there is really just one good tire and more rim doesn't help it.

    No, the tire coefficients shown are not for an Avon tire, the selector is just starting off at the first tire in the list.

    Now 4 the fun part(s)

    A) You need to get into the simplified tire model. It will take out 90% of the trash.

    B) You need a simple (Capture the Essence) vehicle model to evaluate how 4 tires work together in pairs. This...

    Armand Hammer Time

    1) Do the FEA. Why is this such a hard task.

    2) Make up a plastic model and do some fringe pattern analysis (old school).

    3) Build a real to print arm and fixture it. Apply loads, strain gauge...
