Abstract:The contact model of the bearing rolling joint was established based on Hertz contact theory. The finite element model of turret grinding carriage of the compound grinding machine was established in ABAQUS finite element analysis software, in which model, spring damping element was used to replace the bearing roller joint. and the modal analysis of the turret structure was carried out. The modal test and analysis of turret structure are carried out using LMS structure test system. The experimental results show that the finite element modal analysis using spring damping element to simulate the rolling joint of bearing is consistent with the dynamic experimental results, which verifies the feasibility of the method. The replacement of bearing by spring damping element can reduce the difficulty of modeling and provide a reference for the optimization of wheel rotation frequency and turret structure.
