Modified Pipkin-Rogers Modeling of Elastomeric Bushing in Axial Mode [PDF]

한국정밀공학회지, 2017
Elastomeric bushings are structural elements used in automotive suspension systems. A bushing is a hollow cylinder between an outer steel cylindrical sleeve and an inner steel cylindrical rod. The steel sleeve is connected to components of the suspension

A priori error analysis of two force-based atomistic/continuum models of a periodic chain [PDF]

, 2011
The force-based quasicontinuum (QCF) approximation is a non-conservative atomistic/continuum hybrid model for the simulation of defects in crystals. We present an a priori error analysis of the QCF method, applied to a one-dimensional periodic chain ...

Solvable Many-Body Models of Goldfish Type with One-, Two- and Three-Body Forces [PDF]

Symmetry, Integrability and Geometry: Methods and Applications, 2013
The class of solvable many-body problems "of goldfish type" is extended by including (the additional presence of) three-body forces. The solvable $N$-body problems thereby identified are characterized by Newtonian equations of motion featuring 19 arbitrary "coupling constants".

Interaction force modeling and analysis of the human–machine kinematic chain based on the human–machine deviation

Scientific Reports, 2023
A mechanical model for a human–machine interaction force based on the man–machine kinematic chain is established. This is combined with screw theory and a virtual rigid body model for the human–machine interaction force is proposed. This model interprets

Subject-specific body segment parameters' estimation using biplanar X-rays: a feasibility study [PDF]

, 2010
In order to improve the reliability of children's models, the aim of this study was to determine the subject-specific masses and 3D locations of the centres of mass (CoM) of body segments using biplanar X-rays.

Investigation on the basic principles of human-machine contact force, based on screw theory

Heliyon, 2023
In this paper, to introduce a spatial rigid body mechanics analytical method and start the analysis, the human-machine contact force is equivalent to a spatially rigid body: the mechanism and skin surfaces are equivalent to two different rigid planes ...

Experimental Investigation of Subcutaneous Pressure and Shear Force Changes Using a Bone Protrusion Model as a Risk Factor for Pressure Ulcer Development

Journal of Plastic and Reconstructive Surgery, 2023
Objectives: Subcutaneous pressure and subcutaneous shear force were investigated using a bone protrusion model to investigate a polyurethane film dressing (hereinafter referred to as adhesive film) for preventing shear force. Our hypothesis was that when
