A very useful computation in vehicle dynamics is the g-g diagram. What the heck is that? Well... ⤵️ #F1Tech 🏎
Given a car, its set-up, and a velocity, the g-g diagram represents its acceleration envelope: the maximum acceleration the car can perform.
Higher longitudinal accelerations mean the car has more traction and it can brake harder, whereas higher lateral accelerations mean the car can squeeze through tighter corners
What can be used for: have a glimpse on how a car will perform, study different set-ups, detect design flaws, and to learn vehicle dynamics. Data obtained from g-g diagrams is also usually fed to simplistic quasi-steady optimal laptime simulators
How does the car performance vary with velocity? Acceleration decreases (higher drag), lateral acceleration increased (higher downforce), braking acceleration increases (higher drag + higher dwf). In the traction zone, pyramid shape means tire limited whereas flat is engine ltd.
The effect of brake bias its only noted at negative longitudinal accelerations, with braking 60% with the front the best
Aero balance can be analyzed too, having the best cornering dynamics in my particular study case (not in general) with 45% FW and 55% RW
Lastly, we see how critical is the height of the center of mass as it worsens the whole performance of the car as expected
Many other car and setup configurations can be studied! The g-g diagram is a computation module available for free in Fastest-lap! Now available in windows 😊 Head to the link for more info github.com/juanmanzanero/…
