Simulation Study of Rhonrad Mechanism

Abstract

Rhonrad is a gymnastic tool that is interesting in terms of dynamics and control. We presented an analytical model and governing basic equations of the Rhonrad mechanism controlled by a gymnast. Then, we numericaly analyzed Rhonrad motion caused by synchronized sinusoidal linear motion of a mass inside the Rhonrad. By numerical simulation, we clarified the effect of the amplitude and phase of the mass motion on 'Straight-line' and 'Spiral' motion of a Rhonrad.
