The Finite Element Analysis on High Duty Bolted Joints of Slewing Bearing

Abstract:

By reasonable assumption and considering the friction, contact, preload intensity, load eccentricity, bolt bending, and other nonlinear factors, we establish three-dimensional finite element model for the high duty bolted joint to reflect the bolt behavior and develop the finite element calculation method for static strength, fatigue strength and related stresses of bolt. By this method, we do numerous numerical simulation experiments to study the effects of preload intensity, support plate thickness on the bolt behavior. These results will guide designer to complete the slewing bearing design effectively and accurately, and these research ideas can be well applied to bolted joints study in other devices.
