PREDICTION OF RADIAL TIRE’S NATURAL FREQUENCIES

The natural frequencies of a radial tire at a given pressure were determined in terms of the material and structure of the radial tire. With respect to viscoelsticity of rubber, the radial tire was modeled as a ring on elastic tire's body and viscoelastic tread. A natural frequency equation was created on the basis of this model. Experimental values of resonant frequencies at a given pressure are in agreement with the predicted values well.
