I have a pretty good idea of what a car will do beding/twisting wise when you tell it to go, turn and stop, but would like to expand my knowledge and check what I already know. So, what I'm asking of you people is that we get the hard-core chassis tuners/designers/physicists on here and give me some schooling. Hopefully we get some good, QUALITATIVE (don't just spurt out random crap for the sake of sounding pro...) data on here and it will end up being a big help. Thanks!:cool:

Proposed Topics:
-weight distribution and how it changes
-Torque forces on the chassis
-Chassis flex and it's effects on handling.

If there's anything else you'd like to throw in there, feel free:cool:.

Wow! I've done a bit of studying in chassis flex on trucks, so I know that does happen. I was shocked to see what the Toyota did!:shocked:
 
It gets very complicated when dealing with anything besides straight beams, normal geometries, etc. Thank God for NX5 and CAE.
 
If you're looking to accurately predict reactions of a contour's body, I would tell you you'll need about 10 years towards a degree along with several of your friends in other fields to help you model it. :laugh:


Once you leave the land of straight beams and uniform structures things get hairy pretty quick.

Although I guess if you read some static/dynamics books, and strength of material books you could probably make a generic outline of the body of the contour and make massive assumptions to get a rough answer.


Truth be told, go drive your car around corners at a good pace for an hour or two. :cool:

I figured as much:laugh:

I just wanted some basic ideas, but your method is a pretty good idea:laugh:
