A Rott’s pendulum with two degrees of freedom having a two-to-one internal resonance is used to transfer kinetic energy between a rotating disk and an electromagnetic generator. The harvested energy is intended to be used for onboard sensing applications such as tire pressure monitoring system. An analytical model is used to simulate the dynamic response of the pendulum under different rotation speeds of the disk carrying the device. A constant variable speed is also used to look at the behavior of the pendulum with a frequency response-like solution. Bifurcations diagrams are also used to detect periodicity changes of the solutions.

摘要

A Rott’s pendulum with two degrees of freedom having a two-to-one internal resonance is used to transfer kinetic energy between a rotating disk and an electromagnetic generator. The harvested energy is intended to be used for onboard sensing applications such as tire pressure monitoring system. An analytical model is used to simulate the dynamic response of the pendulum under different rotation speeds of the disk carrying the device. A constant variable speed is also used to look at the behavior of the pendulum with a frequency response-like solution. Bifurcations diagrams are also used to detect periodicity changes of the solutions.
