Ouch!

What was the brake problem you had at competition? The disk looked a little chewed. We've been running the Wilwood aluminum rotors for a while, but we are probably going to run steel this year for packaging.

Cheers!

we use Duralcan, which is an aluminum alloy matrix? or something like that.



chewed? you mean on one of our previous cars? the driver's foot feel asleep in the car in a previous year car during the dyno session.



So when he went to do his run on the dynometer, he was full on, on the brakes and then pedal to the metal for the gas pedal, and the disc rotor went into peices

=)



i wasn't part of the team that year... that is just what i hear.



But our brake temps never get hot. after even lapping the car hard we can touch the rotors with our bare hands.



Btw are you guys using ADAMS/CAR model for the kinematics and dynamics analysis?



I can't get head or tails out of that thing... it must be the most user unfriendly software to use.

defprun

That Z brought a tear to me eye

We've pretty much given up on AdamsCar. We can't get s#!t out of it. :/ We use the full SolidWorks package (FlowWorks for the intake), and Ansys for frame analysis.

The brake rotor I was refering to was in the "2003 pictures" section of your teams web page. It just looked like something was hitting it while driving.

We were going to do metal matrix disks in 2002. We got the material and immediately destroyed a couple of very nice ($$) carbide cutting tools on them. We would have to send them out to get cut with a water jet. At that point we decided it wasn't really worth the effort. The loss in weight and increase in braking performance would have been minimal, but if you really wanted to pick nits, there is some engineering justification (to show the judges) to use them. None of our drivers are super fast anyway, so we've got a ways to go before little things like that make a difference in our finishing position.

Good luck

Cheers!

after many weeks i just got the kinematic model working for our rear suspension... i hate adams damn i should've done the equations by hand. It would've been easier to learn numerical methods to solve them then to try to get ADAMS to work.
