different applications. This paper presents an analytical analysis of the transfer of energy between linear
and nonlinear oscillators for free vibrations when oscillators are statically, as well as dynamically,
connected into double-oscillator system, as the two new hybrid systems, every with two degrees of
freedom. The analytical analysis showed that the elastic connection between oscillators caused the
appearance of a like two-frequency regime of time function, and that the energy transfer between
subsystems appears. Also, the dynamical linear constraint between oscillators, each with one degree of
freedom, coupled in hybrid system changes dynamics from single frequency regimes into like twofrequency regimes. The dynamical constraint as a connection between subsystems is realized by rolling
element with inertia properties. In this case, an analytical analysis of the transfer energy between linear
and nonlinear oscillators for free vibrations is also performed.
The two Lyapunov exponents corresponding to each of two eigen modes are expressed by using
energy of the corresponding eigen time component. |
