چکیده
Heterogeneous oscillator networks consist of a dynamical function that describes the state (containing several parameters) and topology reflects connections between oscillators. Revealing macroscopic dynamics systems under different configurations parameters is topic worthy discussion comes with great challenges. In this study, we discuss effect parameter on damped free vibration classical spring network. On regular network, give analytical expression satisfied by system over-damping critical damping. Furthermore, fastest slowest exponential rates decay for conditions. conjunction quadratic eigenvalue theory, extend above analysis from to complex networks. We general method calculating spectrum arbitrary configurations. stability rate rate, also numerical simulation results second largest smallest real parts eigenvalues system. Finally, through comparative results, relax matching relationship three (mass, damping, degree) two (mass damping).

TheDuffing oscillator has become a classical paradigm for illustrating the remarkable jump phenomenon and other nonlinear behaviour [1,2]. The understanding gained on the basis of this low-order nonlinear systemhas helped in the development of reducedorder models of complex mechanical systems ranging from microscales to macroscales [3,4]. The nondimensional Duffing equation with damping and ext...

15 صفحه اولViscous damping identification in linear vibration
Parametric identification of viscous damping models in the context of linear vibration theory is studied. Frequency domain identification methods based on measured frequency response functions (FRFs) are considered. Existing methods are classified into two main groups: matrix methods which use directly the measured FRF matrix, and modal methods which use modal parameters deduced from the FRFs. ...
