TL;DR: In this article, it was shown that higher order subharmonics can exist, depending both on the amplitude and frequency of the parametric excitation of a nonlinear system with hardening springs.
Abstract: A study has been made on the parametric excitation of a nonlinear system with hardening springs. In the parametric excitation of linear systems, the only subharmonic predicted is a subharmonic of order 1/2. However, in the parametric excitation of nonlinear systems, it is shown that higher order subharmonics can exist, depending both on the amplitude and frequency of the parametric excitation.
