    Lets get excited about frequency response.

    So you've got your UG test, but now with the constant speed test we have transient data? Who cares about what the transient test procedure is, as long as...

    The computational performance of the NLP puts processing power into perspective.

    Speaking of ISO test procedures, whats up with the different understeer gradient tests (constant speed vs constant...

    The approach proposed by MCoach and BillCobb will probably save you a whole bunch of time and frustration. I sure wish I had the same advice when I was looked at the tire data back then.

    This is probably when the carpet plots come in handy, and a chirp/pulse/square steer test that was briefly discussed earlier on.

    Imagine if you could combine this steady-state force/moment...

    You can try emailing the SAE event organizers. I've enquired about the same thing about 2 years ago, but they didn't seem to follow through. Hopefully you will have better luck!

    It seems to be a ghost town here, but there is a lot of useful information to digest. I will just go right ahead and ask more questions even if I don't fully understand everything just yet. Maybe...

    I need to convince myself of a few things. Lets plot the lateral acceleration steering gain of an understeering, oversteering and neutral steer bicycle with respect to speed....

    I guess it comes down picking the combination of front and rear cornering compliances I can afford to have then.

    Speaking of simple measurements - if I had nothing in terms of instrumentation,...

    I assume, if I had good confidence in my design-time parameters, the difference between the steady-state simulation and the test result (if I had any) could be attributed to some sort of compliance....

    This is a fresh idea that I think is worth entertaining. Taking the top 3 design finalists represents 2.5% of the total number of entrants at Michigan, but lets start somewhere. Here are some reasons...

    Just for fun, I applied the same technique to some random data I have laying around. Formula North has some nice slaloms for this purpose. Near constant forward velocity, equal cone spacing and...

    I managed to get a simulation up and running. It is an 'idealized' model with no compliance effects and very primitive suspension. Regardless, lets give this a go and see what we get.

    BillCobb,

    You amaze me each time you write something up like this. I am still trying to wrap my head around the 'pre-eggnog' analysis. I am being really slow after I got distracted with another...
