Modelling and analysis of a single gimbal gyroscopic energy harvester

This work investigates the non-linear dynamics of a single gimbal gyroscopic energy harvester, excited by a harmonic moment about 1 and 2 axes simultaneously. The governing equations of motion are derived and a numerical model is developed to analyse the forced system response in all three rotational degrees of freedom. Simulations showing the effect of the harmonic forcing frequency and the gyroscopic damping are presented. The results identify the characteristic motion responses and available power of a single gimbal gyroscopic energy harvester including the development of the non-linear responses.
