  • Analytical tire model for vehicle durability and ride comfort analysis
    Patent number: 6741957
    Abstract: A method of modeling a tire is provided. The tire model is used in simulating vehicle response to a simulated ground profile. The tire has an undeformed envelope that defines the outer circumference when no forces are exerted on the tire. The method includes the steps of mathematically characterizing the tire undeformed envelope and a simulated ground profile. Integrating the characterized simulated ground profile and the characterized tire undeformed envelope with respect to the horizontal direction such that a tire deformed area is determined. Calculating the magnitude of the resultant force vector from the deformed area. Determining the direction of the resultant force vector.
