Enhanced Mid-Flexion Stability in Cruciate-Sacrificing Total Knee Replacement: Impact of Optimized Implant Designs Investigated Using Musculoskeletal Multibody Simulation. [PDF]

open access: yesJ Orthop Res
ABSTRACT Total knee replacement (TKR) is a successful intervention for relieving pain and improving quality of life. In this context, mid‐flexion instability and paradoxical anterior femoral movement remain challenging. However, the role of implant design in cruciate‐sacrificing (CS) scenarios is unclear.

A coupled radial-torsional lumped parameter model of rubber bushing for multibody dynamic simulations [PDF]

open access: yesMATEC Web of Conferences, 2023
Many constitutive models’ finite element (FE) models and lumped parameter models included have been presented for rubber bushings. In general, the FE models cannot be directly used in mechanical multibody systems with bushings, and the lumped parameter ...

An intern-sufficient cloud for large-scale multi-robot systems and its application in multitarget navigation

open access: yesInternational Journal of Advanced Robotic Systems, 2021
Due to generally limited computing capability of an individual robot, cloud-based robotic systems are increasingly used. However, applications in large-scale multi-robot systems will be hindered by communication congestion and consequent lack of ...

Comparing double-step and penalty-based semirecursive formulations for hydraulically actuated multibody systems in a monolithic approach

open access: yesMultibody system dynamics, 2021
The simulation of mechanical systems often requires modeling of systems of other physical nature, such as hydraulics. In such systems, the numerical stiffness introduced by the hydraulics can become a significant aspect to consider in the modeling, as it

Tracking control for underactuated non-minimum phase multibody systems [PDF]

open access: yesNonlinear dynamics, 2020
We consider tracking control for multibody systems which are modeled using holonomic and non-holonomic constraints. Furthermore, the systems may be underactuated and contain kinematic loops and are thus described by a set of differential-algebraic ...

Multibody Modeling and Nonlinear Control of a Pantograph Scissor Lift Mechanism [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2023
In this paper, a new strategy for developing effective control policies suitable for guiding the motion of articulated mechanical systems that are described within the framework of multibody system dynamics is proposed.

Inherent Stability of Multibody Systems with Variable-Stiffness Springs via Absolute Stability Theory

open access: yesComplexity, 2021
In this paper, the inherent stability problem for multibody systems with variable-stiffness springs (VSSs) is studied. Since multibody systems with VSSs may consume energy during the variation of stiffness, the inherent stability is not always ensured ...

Global modes for the reduction of flexible multibody systems

open access: yesMultibody system dynamics, 2021
Modeling a flexible multibody system employing the floating frame of reference formulation (FFRF) requires significant computational resources when the flexible components are represented through finite elements.

Evolution of the DeNOC-based dynamic modelling for multibody systems [PDF]

open access: yesMechanical Sciences, 2013
Dynamic modelling of a multibody system plays very essential role in its analyses. As a result, several methods for dynamic modelling have evolved over the years that allow one to analyse multibody systems in a very efficient manner.
