The influence of discreteness on stress as a result of profiling and tribocontact using the Ansys-modulation method

Abstract

In today's engineering world, where high precision and safety of structures are key priorities, it is important to have the means to investigate and evaluate the maximum stresses of elements as a result of profiling and tribocontact. This task requires innovative approaches and high-tech tools, among which the computer modeling method in the ANSYS environment stands out. In the materials presented below, we will analyze the effect of rolling with a smooth surface and with notches, measure the stress results during the next pressing of the test sample as a result of tribocontact with the press.

Friction and tribology that study the interaction of surfaces in contact, are becoming increasingly important in various industries, from automotive to medicine. Our tests will take place at the yield point of the manufacturing material during successive passage of the rolled product through the profiling stage (rolling with a roller) and the subsequent tribocontact with the press. To reveal the dependence of stresses on the uniformity of contact pairs surfaces, we will examine two variants of profiling: rolling with a smooth roller and with notches, which determines the discreteness of the surface layer. This approach makes it possible to reveal the influence of the surface configuration as a result of profiling with plastic deformation on the maximum and average stresses of the model. An additional task is to confirm the hypothesis of a decrease in average surface tension as the discreteness index increases (transition from a smooth state to a perforated state as a result of profiling).
