Hey Guys,
Just another quick one for today. One of the biggest objections I see to using racecar simulation and the most asked question I get is do you have a circuit model for this track?
Well if you have some race car data this won't be a problem. I show you how to get going with this in 3 minutes here,

It's not the whole story but it shows you what you can do in 3 minutes.
Enjoy Guys

Hey Guys,
Sorry about the lack of posting over the last couple of months. There have been some big projects I have been working on. The good news is there will be some great stuff coming down the pipe for all of you.
In the meantime though I have a treat for you all. Check this out,

This is all centres around using the second order approximation of the traction circle radius vs load characteristic to get going from a blank sheet of paper.

Hey Guys,
I've got a treat for you today. I was contacted recently about a FSAE team about tyre modelling. They where keen to get going with lap time simulation but they where perplexed about tyre data.
This got me to thinking. There is a lot more in ChassisSim than just lap time simulation. Here is a quick run down,

Hey Guys,
I've got something that you can make good use of. One of the untold stories of ChassisSim is how you can use it to evaluate suspension geometry,

You can use the analysis and sim tools to get your head around what the geometry is actually doing and get an idea of what the roll centres, cambers and anti dive and squat are doing.

Hello everybody,
Just a quick community service announcement that ChassisSim v3.29 has been released. You can find out the details here,
http://www.chassissim.com/blog/chass...-been-released
I'll be doing a more detailed tutorial about the rally aspects of it shortly but this should get you up to speed.
All the Best

Hello Everybody!
Today I've got a real treat for you. Find attached the latest episode of Dan's Vehicle Dynamics Corner,
http://www.chassissim.com/blog/chass...-in-chassissim
This is about the vehicle dynamics of rallying and running on dirt and ice. It's a good one so enjoy!

Hello Everybody,
I've just posted the latest episode of Dan's Vehicle Dynamics Corner,
http://www.chassissim.com/blog/chass...simulated-data
It's about the differences and what to look for when using simulated data and how it contrasts with actual data.
Enjoy
All the Best

Correlation
The Vehicle Dynamics industry recognized method for correlating simulation to test is via open loop tests to establish steady state gains, response times, natural frequencies and damping in the linear and nonlinear regions of lateral and longintudinal acceleration. Open loop control inputs via ISO standard tests and computation of system response parameters can dismiss claims that often accompany simulation model demos. These tests only require a few performance signals that kits for these tests can provide.
Arguments for testing race cars for these very same factors are based on the reality of them having a wide linear range and few nonlinear components (except tires (which are just softening springs). Good simulations also reveal that urban legends and fears about using frequency response techniques on race cars are unfounded. They also tend to dismiss the common belief that most of your good cars are neutral steer or oversteer. There's just so much more than weight distribution and tires. Compliances, dynamic geometry, aero and 'large' (low load rating utilization) tires add plenty of complexity and amusement to any vehicle dynamics engineer to investigate. Then you can add a driver...
Now show me the money.

Bill,
Our track record in formulas as diverse as LMP1, P2, V8 Supercars, FIA GT3, F3 and GP2 to name a few should answer this question for you.
However if you really want to be shown the money here you go,

and
http://www.chassissim.com/blog/chass...ne-in-the-elms
and

However if you think you can do better - I'll see you in the market place and we'll see who survives.
