Nonlinear softening and hardening behavior in Helmholtz resonators for nonlinear regimes

Résumé

The governing equation of a Helmholtz resonator considering nonlinear terms of restoring and damping forces is studied. The system is treated by a time multi-scales method and the softening and hardening behaviors of such resonators are detected as functions of amplitudes. Analytically detected responses of the system are compared with obtained results via direct numerical integration of its equation, with continuation and also with experimental results.
