RISAnalytical and Experimental Investigation of Self-Loosening of Preloaded Cap Screw Fasteners
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an effort to establish a theoretical outline of a criterion for preventing the vibration-induced loosening of preloaded threaded fasteners, this paper provides an experimental and analytical ...
A Mathematical Model for Vibration-Induced Loosening of Preloaded Threaded Fasteners
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model is proposed for studying the vibration induced loosening of threaded fasteners that are subjected to harmonic transverse excitation, which often causes slippage between the ...
Novel Formulation of Bolt Elastic Interaction in Gasketed Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Novel formulation was proposed for studying bolt elastic interaction during the tightening of a group of fasteners in flat faced gasketed joints. The model was used for developing tightening ...
