Abstract

Stochastic dynamics of a rotating pendulum is investigated upon the development of a novel wave energy converter. A dependency of the pendulum’s rotational potential on the wave profile is studied. The latter is modeled using a non-harmonic periodic function with a sharp or bent crest. It has been shown that the sharp wave profile significantly deteriorates the rotational potential of the parametric pendulum, so that the system becomes non-rotational even in the primary parametric resonance zone.
