RISVibrations of Fractal Structures: On the Nonlinearities of Damping by Branching
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To study the effect of damping due to branching in trees and fractal structures, a harmonic analysis was performed on a finite element model using commercially available software. The model represented a threedimensional ...
Design and Validation of a Carbon Fiber Collapsible Hinge for Space Applications: A Deployable Boom
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents an analysis and validation of a foldable boom actuated by tapespring foldable elastic hinges for space applications. The analytical equations of tapesprings are described, extending the classical equations ...
Critical Damping Conditions for Third Order Muscle Models: Implications for Force Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results presented in the literature suggest that humans use a position control strategy to indirectly control force rather than direct force control. Modeling the muscletendon system as a thirdorder linear ...
