#5 of 8 Vibration Mechanics by shiphro

May 16, 2005 (11:43 am)

At the Mechanical Engineering college at Temple University in Philadelphia, there is a senior-level class called "Vibration Mechanics".
 
This class dealt with all sorts of vibration and damping. Everything from a door-check (that thing at the top that keeps it from slamming) to the harmonic frequencies of a high-rpm motor and it's mount.
 
After a few months of over / under and critically-dampened systems, response times and harmonic frequencies I came to realize two important pieces of information.
 
1 - I now had more knowledge of how a car handles than 95% of the population.
2 - I was horribly underqualified when it came to suspension design.
 
Once you take suspension into account, the basic formulae governing a car in motion are insanely complex. Four individual springs and dampers all moving while the car accelerates (two expand and two contract), brakes (same, but reversed), turns (same, but side-to-side), goes over bumps and potholes (one to all springs traversing the input).
 
If you can't comprehend those forumlae, you probably should be flipping thru the catalog looking for the highest spring constant.

Hope the link works. Good article about GT40 in expert and less than expert hands at Laguna Seca. Now, what made me feel good was the 1.50.6 that I turned last January, but it was my third day on that track in a 2 month period. I'm sure they all would do better given the time. But a stock engine, 2002 Corvette coupe on street tires was a kick at that speed, and I understand his reluctance to hold the throttle under the bridge, took me most of two days to keep it down going into turn 2. Topped out around mid teens as I remember on that third day.

#7 of 8 Question re: traction & handling by genepep

Can anyone give me a website which would compare automobiles and rate them on the basis of their handling and traction? I realize that this is a subjective matter, but that is still better than nothing.

I would advice you visit local SCCA events, especially autocross (aka Solo2). People are racing their own cars in safe environment. You'll see with your own eyes how stock cars behave when pushed to the limit. You could see BMW, Corvettes, MR2, Rx7, Miatas, Civics, Integras, etc. in stock and modified forms.
 
Usually people get involved in those events at their stock cars, spend some time improving themselves as drivers, understanding vehicle dynamics, etc. After that one could modify the car. There's a lot of suspension products on the market.
 
I would doubt you can find a website you asked for.
