A Rigorous Dynamical-Systems-Based Analysis of the Self-Stabilizing Influence of Muscles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, dynamical systems analysis and optimization tools are used to investigate the local dynamic stability of periodic task-related motions of simple models of the lower-body musculoskeletal ...
A Global Control Strategy for Efficient Control of a Braille Impact Hammer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined control scheme relying on feedback-based local control in the vicinity of periodic system responses and global control based on a coarse-grained approximation to the nonlinear dynamics ...
An Extended Continuation Problem for Bifurcation Analysis in the Presence of Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an extended formulation of the basic continuation problem for implicitly defined, embedded manifolds in Rn. The formulation is chosen so as to allow for the arbitrary ...
Limit-Switch Sensor Functionality Based on Discontinuity-Induced Nonlinearities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Limit-switch sensors are input-output devices that switch operating state in reaction to the crossing of a threshold value of their input. These are used to monitor and control critical values ...
Characterization of Intermittent Contact in Tapping-Mode Atomic Force Microscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tapping-mode atomic force microscopy has wide applications for probing the nanoscale surface and subsurface properties of a variety of materials in a variety of environments. Strongly nonlinear ...
Control of Impact Microactuators for Precise Positioning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrically driven impact microactuators generate nanoscale displacements without large driving distances and high voltages. These systems exhibit complex dynamics because of inherent nonlinearities ...
Discontinuity-Induced Bifurcations in Systems With Hysteretic Force Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the application of the discontinuity-mapping technique to the analysis of discontinuity-induced bifurcations of periodic trajectories in an example hybrid dynamical system in ...
Co-dimension-Two Grazing Bifurcations in Single-Degree-of-Freedom Impact Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Grazing bifurcations in impact oscillators characterize the transition in asymptotic dynamics between impacting and nonimpacting motions. Several different grazing bifurcation scenarios under variations ...
Repetitive Gait of Passive Bipedal Mechanisms in a Three-Dimensional Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The inherent dynamics of bipedal, kneed mechanisms are studied with emphasis on the existence and stability of repetitive gait in a three-dimensional environment, in the absence of external, ...
Erratum: “Co-dimension-Two Grazing Bifurcations in Single-Degree-of-Freedom Impact Oscillators” [Journal of Computational and Nonlinear Dynamics, 2006, 1(4), pp. 328–335]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The matrices in 17,27 should appear as:Display Formulax(t)=(αγcos(ωt−ϕ)−ωαγsin(ωt−ϕ)ωtmod2π)T (17) Display Formuladxdτ=f(x)=(εv−2ζεv−εx+εV2(1−cos(2θ))2(1−x)21)T (27)
