Stress Wave Riveter System Analysis.
Abstract
The Stress Wave Riveter (SWR) is a high velocity metal forming tool. A stress wave is applied by a rapidly expanding magnetic field through a conducting driver plate to the base of a conical steel mass called the stress wave amplifier. The amplifier increases the stress wave in amplitude and duration so that when the wave passes into a rivet the rivet begins to yield plastically. The physics of stress waves requires that the high stress levels be accompanied by high velocity of the medium. The final state of the formed part depends on how that velocity varies with time during the forming period. The report analyzes the relationship between the physical properties of the SWR components and the velocity characteristics produced in the workpiece and in the components of the tool.
