Modeling of three-terminal Flexible Ring Power Network Equipment for power dispatch
2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2016This paper presents a model of three-terminal Flexible Ring Power Network Equipment (FRPNE), which interconnects three 10kV distribution networks to realize closed-loop operation. The main contribution of the models is that they can control the active power flow between three distributed power networks and the reactive power in each distribution ...

The conformation and ring inversion of γ-butyrolactone have been studied using ab initio and flexible model computations. The potential energy surface has been computed using STO-3-21G orbitals and complete geometry optimization as a function of the ring puckering coordinates.

The optical rotatory dispersion of two monocyclic ketones, (R)-3-methylcyclopentanone [R-3MCP] and (R)-3-methylcyclohexanone [R-3MCH], has been investigated under isolated and solvated conditions to explore the role of ring size/morphology and to elucidate the impact of environmental perturbations.

A Discrete Lumped-Parameter Dynamic Model for a Planetary Gear Set with Flexible Ring Gear
Applied Mechanics and Materials, 2011A discrete lumped-parameter model for a general planetary gear set is proposed, which models the continuous flexible ring gear as discrete rigid ring gear segments connected with each other through virtual springs. The ring-planet mesh is analyzed to derive equations of motion of ring segments and planet.

A Flexible Ring Tyre Model for Normal Interaction
2013A physical – numerical tyre model has been developed. The whole model allows to obtain the tyre – road interactions which can be used in vehicle dynamics simulations. In this paper its capabilities in terms of normal interaction analysis are presented. The tyre normal interaction, i.e. the relationship between the normal load and the normal deflection,

Simulation of ring rolling with new wax-based model materials on a flexible experimental machine
Journal of Mechanical Working Technology, 1988Abstract Nowadays, the practice of using model materials for the analogical simulation of most forming processes is well established: however, the practice is almost non-existent in ring rolling. Important new opportunities for ring rolling have arisen due to a remarkable development over the last five years: highly unsymmetrical thin-walled rings ...

Abstract In order to simulate the rubbing characteristics of the single blade-casing system with flexible supports, two types of the self-programmed elements (i.e., two-node Timoshenko beam and spring elements) are adopted to establish corresponding finite element models (FEMs) in sequence.

A rotating ring in contact with a stationary load as a model for a flexible train wheel
2014A load moving on a center-fixed ring and the reciprocal problem, namely a rotating ring subjected to a moving load have been used in several works to study the tire dynamics. In contrast, very few papers exist in which the ring model has been used in order to study the dynamics of a train wheel. In this paper, a thin ring model is introduced to model a

Flexible versus rigid ring annuloplasty for mitral valve annular dilatation: a finite element model.
The Journal of heart valve disease, 1998The study objective was to compare coaptation, and leaflet and chordal stresses in normal and dilated mitral valves (18% annular dilatation) versus valves with flexible (Duran) and rigid (Carpentier-Edwards classic) ring annuloplasty, using a computer model.
