TRANSPORT IN DYNAMICAL ASTRONOMY AND MULTIBODY PROBLEMS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2005
We combine the techniques of almost invariant sets (using tree structured box elimination and graph partitioning algorithms) with invariant manifold and lobe dynamics techniques. The result is a new computational technique for computing key dynamical features, including almost invariant sets, resonance regions as well as transport rates and bottlenecks

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Haptic Devices Based on Real-Time Dynamic Models of Multibody Systems

open access: yesSensors, 2021
Multibody modeling of mechanical systems can be applied to various applications. Human-in-the-loop interfaces represent a growing research field, for which increasingly more devices include a dynamic multibody model to emulate the system physics in real ...

The effect of swingarm stiffness on motorcycle stability: Experimental measurements and numerical simulations [PDF]

open access: yes, 2017
This paper focuses on the effect of swingarm deformability on motorcycle stability and in particular on the weave mode. Multibody models for the analysis of stability and handling of single track vehicles require a lumped element representation of the ...

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

open access: yesEnergy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Dynamics Study of Straddle-Type Monorail Vehicle With Single-Axle Bogies-Based Full-Scale Rigid-Flexible Coupling Dynamic Model

open access: yesIEEE Access, 2019
The longitudinal drawbar and the lateral stabilizer bar of straddle-type monorail vehicle with the single-axle bogies have relatively long structure size. The multibar system leads to deformation during the driving process due to impact loads, even leads

Nonlinear Attitude Control of Planar Structures in Space Using Only Internal Controls [PDF]

open access: yes, 1993
An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are used as means of control so that the total angular ...

Discrete mechanics and optimal control for constrained systems [PDF]

open access: yes, 2008
The equations of motion of a controlled mechanical system subject to holonomic constraints may be formulated in terms of the states and controls by applying a constrained version of the Lagrange-d’Alembert principle.

Robust Linearization and Eigenvalue Analysis of General Complex Constrained Multibody Systems

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The derivation of linearized equations and subsequent eigenvalue analysis is the basis for tasks such as frequency‐domain response analysis, control design, and stability assessment for mechanical systems. However, for general multibody systems with redundant or nonholonomic constraints, practical challenges persist in achieving numerically ...

Deep-subwavelength and hydrostatic-pressure-resistant meta-absorber for broadband low-frequency underwater sound

open access: yesApplied Physics Express
By embedding center-supported graded-circular-plates (CS-GCPs) into an elastomer, a deep-subwavelength and hydrostatic-pressure-resistant meta-absorber was designed and manufactured for sound absorption (SA) under hydrostatic pressure.
