摘要

This paper presents an experimental vibro-acoustic set-up that aims to reproduce the energy pumping phenomenon between an acoustic medium and an essentially nonlinear oscillator. It shows a one-way irreversible transfer of energy between the first acoustic mode in a tube and a thin visco-elastic membrane. Various observed aspects of energy pumping are presented : behaviors under sinusoidal forcing, pumping threshold, resonance capture and transient response.
