This paper presents a method for estimating the fatigue life of polyurethane elastomeric components. A rubber replacement - polyurethane of hardness 80ShA commonly used in vibration damping systems, for example, in motor vehicle suspensions, was used for the study. A metal-rubber bushing component was selected for analysis, and numerical analysis was carried out along with a fatigue model proposal based on a modification of the WangBrown model. The results obtained indicate that the description of the durability process using the proposed relationship is also possible. A constitutive model based on Ogden’s hyperelastic model was identified and verified. The proposed methodology can be used in any part analysis based on the numerical model and fatigue data. The paper also evaluates the effectiveness of other models against the proposed relationship.
