Analysis of the Vibrational Characteristics of a Training Longsword

June 7, 2020 Sean Glover 0

Longswords are often treated as having static vibrational nodes, with implications for sparring. A combination of mathematical analysis, SolidWorks modeling, and practical experiments were used to analyze the motion of a longsword under realistic end conditions. It was determined that not only are the nodes not static with respect to different end conditions, they also vary over time during free vibration after an impulse. Due to the complexity of the vibrations, as well as the very specific design criteria of a sword, it is impractical to attempt to alter the sword to maintain specific node locations. Vibration damping gloves are suggested as a possible remedy to fatigue during sparring.
