METHOD AND DEVICE FOR EVALUATING CORNERING DYNAMIC CHARACTERISTICS OF TIRE

摘要

PPROBLEM TO BE SOLVED: To provide a method and device for evaluating cornering dynamic characteristics of a tire for quantitatively and precisely evaluating inherent cornering dynamic characteristics of the tire in a distance frequency of a comparatively wide range expressed by the frequency of a slip angle input in the tire and a moving speed of the tire. PSOLUTION: In a plurality of input distance frequencies PF(rad/m) expressed by a rolling speed (m/s) of the tire and a plurality of slip angle frequencies f(rad/m) input in the tire, the minimum value PFSB1/SBof at least the input distance frequency satisfies PFSB1/SB≤0.03(rad/m), and obtained dynamic characteristic frequency information is obtained by finding the dynamic characteristic frequency information of the cornering dynamic characteristics to the distance frequency expressed by the frequency of the slip angle and the rolling speed of the tire in a state where the rolling speed and the frequency of the slip angle are set so that the maximum value PFSB2/SBof at least the input distance frequency satisfies 10.0(rad/m)≤PFSB2/SB.
