Thanks to Adrien Gontier of Roues Artisanales and David Linke, I am able to provide you with a unique database of moments-of-inertia and effective rotational masses of a large number of wheelsets. The data allows greater accuracy for VE, a virtual elevation perl script I wrote.
The big surprise is that [...]
The method of Virtual Elevation and all its variants are derived from Newton’s 2nd Law for linear motion, neglecting rotational inertia terms. Do those additional terms play a significant role in elevation-matching? Can we accurately measure the moment of inertia (MOI)? In this post, I’ll describe the terms and provide a [...]
