| Abstract(in English) | In this research, we investigate a parametrically excited pendulum to sacavenge energy from wave power of the ocean. The periodic oscillation and rotation in the parametrically excited pendulum can be constantly-available to extract the dynamical wave energy from the vertical vibration. Mechanical pendulum is arranged to attache on vibration excitor to simulate the behavior of the parametric pendulum. This paper examines the two type behavior: periodic oscillations and periodic rotations. First, we show that the two type motion appears depending on excitation parameters by bifurcation analysis. Secondly, the periodic rotation is examimed the possibility of application to scavenge the dynamical energy from the vertical vibration. However, if the frequency band become broad, another frequency element disturbs the stability of the periodic rotations because the scavenging motion targets the specific frequency. In this report, we examine how the possible behavior for scavenging energy in the mechanical pendulum system with mixed excitation. |
