WebThe first bolt was found to have the maximum force, where the bearing damage was localized and initiated. Staggered bolt arrangements were found to cause significant in … WebJul 15, 2024 · This work studied the fretting response of bolted joint interface under transversal random vibration. A new random fretting test method was developed to reproduce fretting wear damage in real applications of bolted joints. The Gaussianity of the external excitation and the stability of the test system were illustrated by pre-tests.
WebDurbin, Morrow and Petti [6] examined boundary effects of bolted joints when the bolt head diameter (or washer) is 1.5 times larger than the bolt diameter and in the restricted d b /l range of 0.167 to 1.786. They followed the methodology of Musto [10] that was described in the previous section and looked at both edge effects and corner effects.

Webbolted connections are associated with different structural behaviours. In the mechanical model, single-bolt connections are considered as pin joints, while multi-bolt connections are regarded as semi-rigid connec-tions. In FEM modelling, two developed methods, namely 3D model-ling method and simplified modelling method, are usually employed.
