ABSTRACT:
A test machine and method for dynamically testing a tire/wheel assembly. A first laser measurement gage is directed to an inboard rim flange of the wheel to measure radial deflection of the tire/wheel assembly. A second laser measurement gage is directed to the inboard rim flange to measure axial deflection of the tire/wheel assembly. Displacement data and loading data are correlated to provide values for lateral stiffness, radial stiffness and ride stiffness.
