The Influence of Thickness and Interference Fit Ratio on Fatigue Phenomenon: An Empirical Study

In this research paper, interference fit was studied in order to verify the change in the thickness of the models used, as well as the value of the interference fit ratio, and to study its effect on the fatigue phenomenon. Three variables were taken for the thickness of the board: 2, 4, and 6 mm, and three ratios of interference fit: 1.5, 2.4, and 4.7, to see its effect on the phenomenon of fatigue. As the results showed, high pressure is required for the process to pass the pin inside the hole. The deformation value increases with the thickness of the sample. The ANSYS program was used for the purpose of simulation. High pressure is required for the pin to pass inside the hole. The deformation value increases with the thickness of the sample. The highest stress value is 0.063mm, which is the highest value compared to other solutions. It is necessary to obtain results that represent the trajectory on the three axes of the mouth of the pin. The interference fit's pressures and deformations must be used to get findings that depict the route along the mouth's three axes. Changes in the route indicated by the edge of the sample along its length to the center of the pin result in x-axis deformations; it is evident that when the interference fit becomes tighter, the deformation value also rises. In the scenario where the ratio fits 4.7%, deformation has reached 0.1mm, which is the largest amount compared to other instances. The maximum stress value of any known solution is 3.7 GPa. The value of the stresses on the y axis varies throughout the track and rises at the second-third of the axis track length. The deformation value in the situation when the ratio fits 4.7 percent has reached 0.27mm, which is the largest value.
