Abstract
Apparatus for obtaining tire dynamic characteristics in which a wheel and tire assembly is mounted on a shaft assembly of low mass. The tire tread is engageable with either a rotating or stationary supporting surface. Flexible connecting members having load-applying capabilities for urging the tire tread into loaded engagement with the tire supporting surface are located at each side of the tire and connected to the shaft assembly. The desired loading is measured by load cells on the connecting members. The tire may be vibrated at predetermined frequencies and amplitudes in predetermined directions by exciters and the resulting tire dynamic data selectively measured by one or more accelerometers.
