Bolted joints are widespread in various industries. They are used both in detachable and in non-detachable connections. The main requirement for bolted joints is to ensure the strength of the connection and guaranteed contact pressure on the connected surfaces, i.e. joints, during the operation of the structure. As a rule, their design and calculation do not take into account the contact compliance of surfaces, which is determined by their macro- and microroughnesses. This problem leads to an overestimation of the joint strength and an underestimation of the predicted joint compliance. The study proposes a simple model which makes it possible by calculation to take into account the effect of the roughness of the contacting surfaces on the compliance of the joint without modifying the ANSYS application package. On the example of a flange connection, an experimental verification of the adequacy of the proposed model was carried out.
