Fast Generation of Stability Charts for Time-Delay Systems Using Continuation of Characteristic Roots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many dynamic processes involve time delays, thus their dynamics are governed by delay differential equations (DDEs). Studying the stability of dynamic systems is critical, but analyzing the stability of time-delay systems ...
Effect of Delay on Control of Direct Resonance of Ships in Beam Waves Using a Proportional–Derivative Controller With Delay
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A harmonically excited, single-degree-of-freedom time-delay system with cubic and quintic nonlinearities is studied. This system describes the direct resonance of a ship with an actively controlled antiroll tank (ART) that ...
Muscle Constitutive Model With a Tangent Modulus Approximation: Ansys Implementation and Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sophisticated muscle material models are required to perform detailed finite element simulations of soft tissue; however, state-of-the-art muscle models are not among the built-in materials in popular commercial finite ...
Phenomenological Muscle Constitutive Model With Actin–Titin Binding for Simulating Active Stretching
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The force produced by a muscle depends on its contractile history, yet human movement simulations typically employ muscle models that define the force–length relationship from measurements of fiber force during isometric ...
Stability of Human Balance With Reflex Delays Using Galerkin Approximations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Falling is the leading cause of both fatal and nonfatal injury in the elderly, often requiring expensive hospitalization and rehabilitation. We study the stability of human balance during stance using inverted singleand ...
Pole Placement for Time-Delayed Systems Using Galerkin Approximations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many dynamic systems of practical interest have inherent time delays and thus are governed by delay differential equations (DDEs). Because DDEs are infinite dimensional, time-delayed systems may be difficult to stabilize ...
Pole Placement for Delay Differential Equations With Time-Periodic Delays Using Galerkin Approximations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many practical systems have inherent time delays that cannot be ignored; thus, their dynamics are described using delay differential equations (DDEs). The Galerkin approximation method is one strategy for studying the ...
Is My Model Good Enough? Best Practices for Verification and Validation of Musculoskeletal Models and Simulations of Movement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational modeling and simulation of neuromusculoskeletal (NMS) systems enables researchers and clinicians to study the complex dynamics underlying human and animal movement. NMS models use equations derived from ...
