摘要

Instruments for surgical and dental application based on oscillatory mechanics submit unwanted vibrations to the operator鈥檚 hand. Frequently the weight of the instrument鈥檚 body is increased to dampen its vibration. Based on recent research regarding the optimization of granular damping we developed a prototype granular damper that attenuates the vibrations of an oscillatory saw twice as efficiently as a comparable solid mass.
