Calculating forces on a Moncoque chassis

[wicz]

Hi There,

This is my first post but hopefully you can help me,

Im a 2nd Year Motorsport Engineering student, I've been set the task of doing a short presentation on how you calculate the forces acting on a car chassis, with some example calculations.

My classmate and myself have backed ourselves into a corner slightly by choosing to do this on the Monocoque chassis, which I am majorly struggling with! Wishing we had chosen spaceframe now!

Would be great if someone could point me in the direction, or maybe recommend a paper or technical report?

Thanks in advance!
Max

give you an example of loads during cornering..now as far as chassis strength
relative to roll over and crash strength...a little reverse engineering would be in order
i would consult the rule book of the sanctioning organization for minimum build spec for the car class, then calculate the components strength accordingly..I know Nascar spent a ton of money researching this exact point after Dale T boned the wall at Daytona..the specs may be way over engineered ..but you can bet your ...life..they are safe..

Thanks! I will give that thread a read
