Vibration isolation of lumped masses supported on beam subjected to varying excitation frequency by imposing node method

Stability analysis of discretized structure systems based on the complex network with dynamics of time‐varying stiffness

“…From the perspective of research, their common characteristics are discretizable; that is, they can be partitioned theoretically into different discrete elements interconnected, and thus, the dynamic analysis for whole system is transferred to analyze the dynamics of elements interconnected. Such discretization methods include mainly the lumped mass methods, [18][19][20] the generalized coordinates methods, 21,22 and the finite element methods. [23][24][25][26][27] In the past decades, by employing the above methods, there has been growing interest for the discretizable structural systems in displacement-based stable design because the displacements provide a more fundamental expression for the response to external forces.…”
