Abstract

Based on the operating principles of rolling bearings and actual boundary conditions, using the SKF6180 deep groove ball bearing as a reference, a dynamic simulation model was established based on the ANSYS Workbench platform. Structure and modal analysis were conducted under the free and constrained model conditions for the bearing system, obtaining low-order modal frequencies and vibration modes. The results indicate that the self-vibration frequency of the bearing under constrained conditions is significantly higher than under free modal conditions. When the inner ring of the deep groove rolling bearing is constrained, the critical speed of the bearing system is highest, exhibiting optimal dynamic characteristics. Through modal and vibration mode analysis of the bearing, it shows that the dynamic stability of the cage is relatively weak, making it an improvement target for enhancing the dynamic characteristics of the bearing system. By applying appropriate constraint boundary conditions, the dynamic characteristics of rolling bearings can be effectively improved, providing a solid basis for engineering applications and structural optimization of bearing products.
