Résumé: Shrink-ft assemblies have been used to ofer a more robust running surface for wooden wheels for a long time. Generally, the two parts are cylindrical or conical. Shrink-ft is now an operation that involves creating contact between two cylinders, there is no third party, and this is good economically. It’s employed in a variety of industries, including automotive, aerospace, oil and gas, and train wheels. To do this operation, the inner cylinder’s outer radius must be greater than the outer cylinder’s inner radius, that diference between them is called ’interference’, the latter is being important in the assembly because it contributes to increasing the resistance of the assembly. There are three ways to do this: the frst by heating the outer cylinder until it expands, the second by cooling the inner cylinder until it shrinks and the third way is to realize the ftting under a press. When two cylindrical components are assembled by pushing or shrinking one onto the other, at the interface between the two matching parts, a contact pressure and friction force is formed. We study a shrink-ft assembly made up of two hollow cylinders in this paper, taking into account that the contact surfaces are not perfect but contain form defects, we try to know the efect of form defects and their role in the cohesion of the assembly using numerical simulation
