Abstract
Dynamics of the gyroscopic power generator is studied which produces high speed rotation of magnets from low-frequency vibrations such as human body movement. First the equation of motion of the rotor is derived. Next, the equation is solved numerically and the effects of initial conditions, damping coefficient, inertia moments and axis radius on the stability of rotation are clarified. Also a design guideline for the stable generator is presented. Next an approximate solution for the transient response is obtained to clarify the mechanism of transient vibration. Finally, the transient response is observed experimentally and the validity of the numerical and approximate analyses is verified.
