“…As results from numerical simulations for J3-J15 joints, increasing interference increases the value of the assembly force of the joint, but does not significantly increase the value of the joint breaking force. The observation is in line with those in the paper [10]. This is due to the plasticization of the entire contact surface occurring along the entire length of the joint and continuing deeper into the joined elements.…”

“…The surface pressure value and the value of the maximum force breaking the joint, calculated according to Formulas (1) and ( 4), are presented in Table 2. In each of the considered types of fit, the joints are assumed to be elastic in nature and the friction coefficient is µ = 0.1 [10]. Calculations in Formula (4) were performed assuming roughness of Ra = 0.4 obtained by finishing turning.…”

“…Article [9] presents the results of numerical tests and simulations concerning the increase in the load capacity of joints by using an adhesive. In [10], two discrete models, which use surface and spatial finite elements, were applied to simulate the joint. However, the relative error of the simulation compared to the experiment was 10% (2D model) and 15% (3D model).…”

Interference fit joints have been widely used in many engineering constructions, in particular in electric motors. It is of particular importance to calculate the load capacity of press-fit joints, especially in the overload ranges of construction to estimate the safety factor. The article presents a FEM numerical simulation of pressing the shaft into the hub, taking into account various types of fits. The results of numerical simulations presented in the article were positively verified with the MTS measuring device, which confirmed the correctness of the numerical model. So far, the load-bearing capacity of press-fit joints has been calculated from Lame’s formulas. The results of the load capacity of the joints obtained by the FEM simulation were compared with the results obtained from Lame’s formula. The comparison shows that when designing interference fit joints, attention should be paid to the fact that the press-in process, depending on the type of fit, may be elastic-plastic. Plastic deformations in the contact zone of the joint affect its load-bearing capacity. Therefore, the design of press-fit joints should not be based on Lame’s formulas, which do not take into account the range of plastic work of the material.

“…Połączenia wciskowe znajdują szerokie zastosowanie w konstrukcjach inżynierskich, a zwłaszcza przy łączeniu wału z wirnikiem w konstrukcji silników elektrycznych. Połączenia tego typu były analizowane w rozmaitych aspektach w wielu pracach [1][2][3][4][5], niewiele jest jednak badań eksperymentalnych weryfikujących wyniki obliczeń numerycznych dotyczących nośności tych połączeń. W połączeniu wciskowym wzajemne unieruchomienie łączonych części następuje wskutek tarcia wywołanego przez wcisk.…”
