This thesis presents, explores, and documents the validation of a mechanical mechanism dubbed Vibration-Induced Rotation, or VIR. The tendency of threaded fasteners to move under the influence of vibrations is well known, but never before has the root cause been identified and investigated in search of beneficial consequences. The sense of rotation, speed, and force with which a threaded body moves in an appropriately vibrated medium is a function of the excitation. The principal kinematic and dynamic relationships governing VIR have been developed and experimentally affirmed. There is evidence for more complex modes of motion, but pure VIR remains the dominant response under a wide variety of conditions. Simplicity, robustness, and uniqueness suggest a multitude of possible applications, particularly in the areas of product assembly and fastener insertion. This thesis should provide a cornerstone in a new and promising field of application-oriented research.
