Yes that's fair for this example. In regards to the original question 'tables vs math' the size still depends on which tables you use, resolution, their coordinate system etc.Originally Posted by Z
The literature suggest that this is actually a decent assumption until you get into tire/ground interaction.Originally Posted by Z
Couple sources that come to mind:
Georg Rill, SAE Paper 860575
Halliday, SAE Paper 983030
OK, I just want someone to show objective proof of this.
Here's my two cents for the morning:
Made a little dynamic simulation in MATLAB. 2nd order SMD with a nonlinear (quadratic) spring.
Using the direct math solution F=k*x*x is 100 times faster than a lookup table, even for low resolution.
(Yes it's not compiled and yes trig calculations use something close to lookup tables + polynomials...
I don't have a lap simulator to test this, maybe someone who does could compare and show their objective proof?)

Code attached; as per usual, change '.txt' to '.m' to run.
