The subject of the following article is the problem of predicting fatigue strength and durability of wheels constructed as an assembly of a rim and a disc, for large dimension wheels. Such wheels are widely applied to supersize cars, tractors, combine harvesters and other agricultural and road machines Considered are the main problems occuring when creating a FEA model for various loading conditions, including bench test and technological ones. 3 versions of the item production, depending on the contact conditions of the disc and the rim during the interference fit assembly followed by welding, have been analyzed. Recommendations on decreasing of stress-strain state in the most unsafe points of the construction have been given.
