RISProspects for Nonlinear Energy Harvesting Systems Designed Near the Elastic Stability Limit When Driven by Colored Noise
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ambient vibration sources in many prime energy harvesting applications are characterized as having stochastic response with spectra concentrated at low frequencies and steadily reduced power density as frequency increases ...
Axial Suspension Compliance and Compression for Enhancing Performance of a Nonlinear Vibration Energy Harvesting Beam System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Developing energy harvesting platforms that are strongly sensitive to the low and diffused frequency spectra of common environmental vibration sources is a research objective receiving great recent attention. It has been ...
A Disturbance Cancellation Perspective on Vibration Control Using a Bistable Snap Through Attachment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One approach to vibration control is to apply a force to a primary structure that opposes the excitation, effectively canceling the external disturbance. A familiar passive example of this approach is the lineartuned mass ...
Enhancing Structural Damage Identification Robustness to Noise and Damping With Integrated Bistable and Adaptive Piezoelectric Circuitry
