Analysis and modeling of the radial force in a switched reluctance motor with sinusoidal excitations [PDF]

open access: yes, 2010
Due to its special structure, the shaft radial force and torque of three-phase 12/8 switched reluctance motors can be independently controlled by proper distribution of currents at each pole of the excited phase.

Eccentric Rotor Drop Dynamics Study of Vertical Maglev Bearing System

open access: yesLubricants, 2023
When considering the problem of a vertical magnetic levitation bearing system, the rotor eccentric fall is more likely to cause the failure of the protective bearing. In this paper, a rotor drop collision model and a protective bearing dynamics model are

Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]

open access: yes, 2013
Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (

Radial Forces in a Misaligned Radial Face Seal [PDF]

open access: yesJournal of Lubrication Technology, 1979
Radial forces on the primary seal ring of a flat misaligned seal are analyzed, taking into account the radial variation in seal clearance. An analytical solution for both hydrostatic and hydrodynamic effects is presented that covers the whole range from zero to full angular misalignment.

On compressive radial tidal forces [PDF]

open access: yesAmerican Journal of Physics, 2007
Radial tidal forces can be compressive instead of disruptive, a possibility that is frequently overlooked in high level physics courses. For example, radial tidal compression can emerge in extended stellar systems containing a smaller stellar cluster. For particular conditions the tidal field produced by this extended mass distribution can exert on the

Experimental system for measuring the force load of a single blade pump [PDF]

open access: yesMATEC Web of Conferences, 2023
Precise evaluation and anticipation of the radial and axial force loads acting on the impeller of a spiral casing pump are essential to ensure that the pump operates efficiently and dependably. This study presents an experimental system for measuring the
