Modal Testing and Identification of Lower Order Tire Natural Frequencies of Radial Tires
- Ground Vehicle Standard
NOTE 1—The focus of this standard is identification and reporting of the lower order natural frequencies of the tire using a simple test procedure. While higher order natural frequencies may be excited during these tests, the reliable identification of the associated mode shapes is not addressed in this document.
NOTE 2—Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular surfaces, paved or otherwise. Within the context of this document, forces applied to the road or terrain surface are not considered.

The Vehicle Dynamics Standards Committee (VDSC) reports to the Vehicle Performance Steering Committee. The VDSC develops Information Reports, Recommended Practices and Standards related to the dynamics of passenger cars and light trucks, excluding trailers. The committee establishes tests and analyses that contribute to the understanding of the ride and handling performance of the total vehicle as a dynamic system.
