RISOn the Vibration of a Point-Supported Linear Distributed System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The vibration of a constrained dynamical system, consisting of an Euler-Bernoulli beam with homogeneous boundary conditions, supported in its interior by arbitrarily located pin supports and ...
Isolated Resonance Captures and Resonance Capture Cascades Leading to Single- or Multi-Mode Passive Energy Pumping in Damped Coupled Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We examine passive energy pumping in a system of damped coupled oscillators. This is a one-way, passive and irreversible energy flow from a linear main system to a nonlinear attachment that ...
Experimental Testing and Numerical Simulation of a Six-Story Structure Incorporating Two-Degree-of-Freedom Nonlinear Energy Sink
Publisher: American Society of Civil Engineers
Abstract: The nonlinear energy sink (NES) is a fully passive attachment used to rapidly dissipate a significant portion of energy induced in a linear primary structure to which it is attached. In this study, the performance of a ...
