Variational multirate integration in multi‐body dynamics [PDF]
PAMM, 2016 AbstractFor systems that contain slow and fast dynamics, variational multirate integration schemes are used. These schemes split the system into parts which are simulated using two time grids consisting of micro and macro nodes. This formulation can be extended for multi‐body systems.

Dynamic modeling and characteristics study of airdrop folding multi-body aircraft
Xibei Gongye Daxue XuebaoIn the processes of launch, development and fall at high altitude without initial velocity, the dynamics model of a folding multi-body aircraft shows the characteristics of a multi-rigid body and multi-degree of freedom. The relative motion of each rigid

Method for Analysis of an Offshore Heave Compensator
Applied Sciences, 2016 A heave compensation system consists of a drill string compensator (DSC) and an active heave compensator (AHC) cylinder, which together produce control force over an oil pressure system suitable for transmission of considerable power and compensating for

Acoustic manipulation of multi-body structures and dynamics
Reports on Progress in PhysicsAbstract Sound can exert forces on objects of any material and shape. This has made the contactless manipulation of objects by intense ultrasound a fascinating area of research with wide-ranging applications. While much is understood for acoustic forcing of individual objects, sound-mediated interactions among multiple objects at close ...

Inverse and forward dynamics: models of multi–body systems [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003 Connected multi–body systems exhibit notoriously complex behaviour when driven by external and internal forces and torques. The problem of reconstructing the internal forces and/or torques from the movements and known external forces is called the ‘inverse dynamics problem’, whereas calculating motion from known internal forces and/or torques and ...

Multi-Body Dynamics Simulation of Hoisting Wire Rope and Its Stress Analysis
Xibei Gongye Daxue Xuebao, 2020 As a key component of the hoisting system of the crane, the steel wire rope will bear a variety of loading actions such as stretching, bending, vibration and impact in the process of traction hoisting.

Multi-body Dynamics Study of Gears [PDF]
, 2022 Gear faults can usually occur due to fatigue, spalling or pitting caused by wear, load fluctuations, backlash etc. This severely reduces actual strength of the gears and prompts crack growth. Fatigue cracks may appear in the region of highest stresses, whose location can be determined based on numerical analysis, meshing force variability, point of ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
