Dynamics Calculators



  1. Our physicists’ team constantly create physics calculators, with equations and comprehensive explanations that cover topics from classical motion, thermodynamics, and electromagnetism to astrophysics and even quantum mechanics.

Suspension Dynamics Calculator

OK, here is the motherload.

This is a web-based version (slightly simplified) of the Excel spreadsheet I designed and used to work out all the various calculations needed to properly set up the car.

Product Usage Estimators from American Dynamics by Tyco Security Products - Bandwidth and Storage Calculator, Camera Placement Tool, and System Resource Estimator.

Physics Equation Calculator

Yes, the graphs don't work in Internet Explorer (download Firefox already, all four of you who still use IE!)

The remaining work on it is to provide a data entry block for your own shocks (to compare against the theoretical ideal)

The key to using this application is Accurate Measurement. There's a lot of data you have to pull off the car and accuracy counts!

Remember: Garbage In, Garbage Out!

Some of the data is fairly simple to collect (like corner weights). Others, (like CG height and roll centre height) take a little more work.
