摘要：
Here, the contact model of bearing rolling joint was established based on Hertz contact theory, and a spring- damping element was used to replace bearing roller joint. Finite element model of composite grinder grinding carriage turret was established using the finite element analysis software ABAQUS, and modal analysis was performed for turret structure. Modal testing and analysis were conducted for turret structure using LMS structural test system. Tests showed that the finite element modal analysis results with spring-damping element to simulate bearing rolling joint is consistent with dynamic test results to verify the feasibility of this method; replacing bearing with spring-damping element can reduce the difficulty of modeling and provide a reference for optimizing working rotating frequency of grinding wheel and turret structure. © 2024 Chinese Vibration Engineering Society.
