The Hanging Point of the Spatial Grid Structure High Strength Bolt Fatigue Notch Effect Analysis

Abstract:

In recent years, the advantages of light weight steel structure with its widely used in long-span space truss structure industrial workshop. Unlike traditional bridge crane, space truss structure plant can use suspension crane, so the dynamic load of fatigue problem worthy of further study^[. The fatigue of the space truss structure including: structure component fatigue, tired of hanging lifting point. At present, the fatigue test is the most reliable research method. This article uses the ANSYS software for welding the hollow ball nodes ^[2] hanging points of high strength bolts in finite element simulation analysis, observation under the effect of unilateral axial tensile force, the stress distribution of high strength bolt, and calculate the stress concentration factor in thread.
