The relationship between the power flows and the parameters of the oscillators and couplings have been studied. It is shown that the indirect power flow is caused by the resonant transmission between the indirectly coupled oscillators. Once the parameters of the oscillator elements have been settled, the indirect power flow is mainly determined by the coupling stiffness k3 and k4, and is less infiuenced by coupling dampings c3 and c4. The indirect power flow cannot be ignored in strong coupling conditions. Because of the resonant transmission between the indirectly coupled oscillators, the indirect power flow still cannot be neglected even if the coupling stiffness is relatively small and the coupling damping is relatively great展开更多

It is shown that the power flows among the three non-conservatively series-coupled oscillators, similar to that of the three conservatively series-coupled oscillators,include the direct and indirect power flows. The direct and indirect power flows are proportional to the differences of the stored energies in the directly coupled and indirectly coupled oscillators. The proportionality constants are functions of parameters of the oscillators and couplings展开更多
