MODEL OF RADIAL DEFORMATIONS OF PROTECTOR OF VEHICLE TIRE

Abstract

Numerical and experimental investigation results in order to find out stiffness of the tire protector, as single element in dynamic models of a suspension are presented in this paper. Numerical modeling demonstrated that de-scription of ribbed part with the evaluation of pattern fill-ing coefficient was adequate to rubber prisms deformation models. Testing confirmed that in numerical models it was necessary to evaluate constriction of protector's deforma-tion by rigid breaker and cord layers, that is why radial deformation of the protector decreases 1.7 - 2.1 times. Tak-ing into account unevenness of contact surface stiffness-loading dependence does not bring qualitative changes. With more correct evaluation of operational conditions of the protector layer results coincide with testing results.
