摘要
Abstract Taking the rough surface of C45 steel grinding as the research object, we established a two-dimensional finite element model of the rough surface and its surrounding air by using ANSYS, and studied the contact properties between the rough surface and the rigid plane under normal load (≤ 10MPa). On this basis, ANSYS Apdl language was used to establish a force-magnetic coupling model, and further simulated the impact of different load conditions on the leakage magnetic field on the contact surface. The results showed that according to the zero-crossing point of the normal component of the leakage magnetic field or the extreme point of the tangential component, the number of stress concentrations on the contact surface and the stress level of the corresponding area can be effectively determined. This method has certain reference value for studying the surface contact stress distribution between parts.
