Finite Element Analysis Method for Mechanical Properties of Elastic Steel Ball Bearings
摘要
Abstract
In long-span spatial structures,bearings playan important role as a connection between the upper and lower parts of the main structure.It is of great importance to studymechanical performance of bearingsunder actual external loads.Based on ABAQUS,finite element analysis ofelastic steel ball bearings in a typical largespan spatial structure was conducted.Comparing bearing stiffness obtained from the finite element analysis withthe norminal value,rationality of thefinite element model was verified.The in-depth finite element analysis results show the stress state of elastic steel ballbearing,whichprovides a reference of simplified analysis of such bearings in large-span roof structures.关键词
