Abstract
In this paper, analytical analysis of the vibrational tristable energy harvester with a RL resonant circuit is presented. The analytical solutions of the steady-state response displacement and the steady-state output voltage are derived via the method of multiple scales. The influence mechanism of the excitation amplitude and frequency, the electromechanical coupling coefficient, the damping and the detuning parameters on the dynamic response characteristics and the output voltage is studied. In order to enhance the energy harvesting performance, the appropriate choice of the excitation amplitude and the electromechanical coupling coefficient is discussed.
