Longitudinal & Lateral Velocity Calculation

[JAlbert]

thread108-331895

I have been looking thought had a look through the Excel spreadsheet for the bicycle model and I have found the references for all the calculations very interesting especially form "Fundamentals of Vehicle Dynamics" and "Race Car Vehicle Dynamics" these two books I will definitely be purchasing as they are a great read. However, when coming across the Longitudinal & Lateral Velocity Calculations I had seen the formula and don't know where it has come from or how it was derived. Could anyone please explain how these formulas were created as it is a very interesting approach that I have not seen in other papers online.

This excel was not created by me but by HJsimpson (Mechanical)(OP)

I don't know, debugging other people's excel is not my hobby, but I don't like it. try t=10,or 1. Even for more sensible values, the slip angles should stay the same.

Cheers

The spreadsheet defines the formula and source Tires, Suspension and Handling, 2nd Ed, p.350

I found the index online, but the book is not free.

This gives some insight
