Help with tire testing

[Tincho]

Hello everyone or anyone,

Some years ago a read a post about tire testing with a trailer rig (tire dynamometer).

It tested slip angle vs lateral force.

The procedure was really well explained

I have been looking for it for the past week and can't seem to find it.
Can anyone give me a hand

Much appreciated!

Abstract: Tire force and moment testing is a valuable way of quantifying the performance of a tire. The data collected from such
testing is also used by many researchers for vehicle dynamic simulation studies as well as chassis control system development.
Although various studies have claimed correlation between data from rolling road type machines and road testing trailers, the claim
only extends for on-road conditions. Many military vehicles as well as agricultural vehicles operate in an environment which requires
new levels of tire test data. This paper will discuss the design and testing of a portable trailer tire test rig. This rig was conceived and
constructed for use on both on- and off-road driving surfaces and is also fitted for wet-road testing. The rig will eventually be used to
collect tire data on various tire sizes both on and off-road on various road surfaces, such as grass, asphalt, concrete, and gravel for
varying speeds, pressures, loads, and slip angles. The data will be used to develop a modified Pacejka Magic Formula Tire Model that
can be used for conducting simulation in both on and off-road conditions.

Bill, Do you know if this Virginia Tech trailer is still in use? Last I heard it wasn't being used very often, but that was several years ago.

Nope. I'd tell them to starin gauge a brake rotor as Toyota shows in a paper they wrote on it.

Thank you very much Bill!!
