Analysis of hammer movement based on a parametrically excited pendulum model
(Analyse der Hammerbewegung basierend auf einem parametrisch angeregten Pendelmodell)
Motions of the hammer were analyzed to understand the mechanism of acceleration with a hula-hoop model using an energy pumping mechanism. The condition that makes the time derivative of the energy positive is derived as energy pumping for hammer. The condition is expressed in terms of the tugging force times velocity to pump the hammer energy. In this study, motions of the hammer were analyzed and numerical experiments were performed to examine the validity of the theory.
