Thank you very much Bill! Super interesting!

agree, this forum has always been a source of great discussions and information. Would be a pity to somehow loose it.

question for all of you:

being this Yaw Center on car center line, shouldn't it only tell how much of the overall Yaw moment is coming from the front and rear axle? considering also Yaw Moments'...

hillclimb tires? :)

Anyway, regarding the front weight distribution, i guess one thing which still deserve to be mention is the differential.

In my experience, it could change dramatically how...

second part, diagrams.

@jpusb,

yes, i correct the corner radius for each output point of the diagram. Actually, since it is a constant velocity simulation, calculating the Fy gives automatically an Ay, so the radius is...

Jpusb,

here a picture showing the slip curve of a front tire i am using, with vetical loads varying between 2000 and 6000N.

What is the point exactly in simulating the longitudinal forces if...

After the discussion has deviated a bit, i would like to redirect it a bit on the original topic, the yaw moment diagram and its use.

I would love to have the feedback of more expert people about...

Hi everybody,

my apologies for not coming back earlier after all your comment.

i revised my work on the YMD basing on your suggestions and comments, also because i actually found something...

From direct experience, reverse engineering the tire is a nice technique if you don't have any data at all, but it is at the same time very dangerous, above all if your driver is, for any reason, not...

hi guys,

first of all thanks a lot to everybody contributing to this thread. Really interesting.

I built up myself a tool in excel to create the Yaw Moment Diagram of a vehicle and would like...

Interesting discussions going on here.

Z, your input is always very interesting, above all from theoretical perspective. I always got some very good food for though reading your comments, but...

of course a fsae team have the same budget, the same skills, the same experience and the same knowledge as nissan....so it should be pretty easy!

didn´t have time to look at it properly yet.

Just one question anyway: does it allow to model Push/Pull Rod geometries by default, or they should be defined somehow by the user?

first of all thanks to all the contributors of this thread. It is really a great and informing one.

Going through all your comments pushed me to go again through some "theory" that i realized i...

Tim

regarding the feasibility of Stability index for on-track studies (data engineer typical work, race engineer as well in many teams), i think it doesn't work as it is.

The assumptions made...

i am totally with Tim...

I tried to take out the same channels both on sim and real data, but no success on really using it for stability evaluation. Sometimes, a part from the noise mentioned by...

Danny,

thanks for your reply.

i understand your point and this explanation was already pretty clear from your paper.

Anyway, what i meant is that, if you change the max load value, the...

Hi Danny,

first of al thanks for your posts and the material you publish.

Would be nice to have something new more often, but i understand it's not good for your business to show your...

you can do it, but to build up a car in rF is a long, long trip. And you need data that probably you don´t have before to run the car.

Anyway, in my opinion, it is all about how much time you can...

Hi,

very interesting work and very useful tool for all Fsae teams around the world.

I have a question about your autocross or endurance part of the code: when looking for the maximum corner...

Why a parallel arms layout should be considered a bad design? I see a lot of good things in it.

Of course if the car is really stiff in roll then camber gain is not anymore an issue, but also if...

my question is connected also to how the shape of the curve is changing in real life when the road grip is changing.

Do we have to expect the tire to reach maximum force at different slip angles...

Hi,

i have tried to look on the forum for an answer to my question, but didn't find anything useful.

I am using tire data from TTC, but need to correct maximum grip because, as reported in...
