Abstract
Systems and methods, including: one of a simulated road surface and an actual road surface; a test tire physically contacting the one of the simulated road surface and the actual road surface; and a plurality of gears linking the test tire and the one of the simulated road surface and the actual road surface, such that the velocities of the test tire and the one of the simulated road surface and the actual road surface are linked and an associated slip ratio between the test tire and the one of the simulated road surface and the actual road surface is controlled. The simulated road surface includes one of a drum, a belt, a drive wheel, and a rail. The plurality of gears are varied in terms of gear ratio using a controller such that slip ratio is dynamically controlled and varied.

A tire testing system, comprising:
- one of a simulated road surface and an actual road surface;
- a test tire physically contacting the one of the simulated road surface and the actual road surface;
- and
- a mechanical linkage linking the test tire and the one of the simulated road surface and the actual road surface, such that the velocities of the test tire and the one of the simulated road surface and the actual road surface are linked and an associated slip ratio between the test tire and the one of the simulated road surface and the actual road surface is controlled.
A tire testing method, comprising:
- providing one of a simulated road surface and an actual road surface;
- providing a test tire physically contacting the one of the simulated road surface and the actual road surface;
- and
- providing a mechanical linkage linking the test tire and the one of the simulated road surface and the actual road surface, such that the velocities of the test tire and the one of the simulated road surface and the actual road surface are linked and an associated slip ratio between the test tire and the one of the simulated road surface and the actual road surface is controlled.
A tire testing system, comprising:
- a first rail and a second rail, wherein one or more of the first rail and the second rail comprise separate substantially horizontal and substantially vertical plates;
- a carriage assembly coupled to the first rail and the second rail such that five degrees of freedom of motion of the carriage assembly are thereby constrained;
- a first bogie assembly coupling the carriage assembly to the first rail such that at least lateral, pitch, and yaw motions of the carriage assembly are thereby constrained;
- and
- a second bogie assembly coupling the carriage assembly to the second rail such that at least vertical and roll motions of the carriage assembly are thereby constrained;
- wherein the carriage assembly translates in a direction that is tangential to the first rail.
