Self-Loosening Model for Bolted Assemblies under Transverse …

WebThe present article investigates self-loosening of bolted assemblies under the effects of transverse loads. Firstly, we discuss the relaxation phenomenon that occurs at the end of tightening. We then perform modeling and calculus for self-loosening conditions for a short screw, neglecting the tilt of the screw in its tapping. WebIn general terms, the key to preventing self loosening of fasteners is to ensure that: 1. There is sufficient clamp force present on the joint interface to prevent relative motion between the bolt head or nut and the joint. 2. … harold ford\u0027s family https://urschel-mosaic.com
