Flexural vibrations of rotating beams considering rotary inertia

Computers & Structures, 1998
Abstract The effects of rotary inertia on the extensional tensile force and on the eigenvalues of beams rotating uniformly about a transverse axis taking into account longitudinal elasticity are analyzed in this work using the perturbation technique and Galerkin's method.

Influence of rotary inertia on the fiber dynamics in homogeneous creeping flows

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2007
AbstractThe rotation of an inertialess ellipsoidal particle in a Newtonian fluid has been firstly analyzed by Jeffery [1]. He found that in the shear flow the particle rotates such that the end of its axis of symmetry describes a closed periodic orbit.

On the Appropriate Rotary Inertia in Timoshenko Beam Theory

International Journal of Applied Mechanics, 2021
The rotary inertia defined by Timoshenko to account for the angular velocity effect in flexural vibration of beams has been questioned by some researchers in recent years, and it caused some confusions. This paper discusses the appropriate rotary inertia in Timoshenko beam theory (TBT) and evaluates the influence of the two forms of the rotary inertia

The “Feel” of Rotary Controls: Friction and Inertia

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1966
The purpose of this study was to determine the influence of friction and inertia levels on the “feel” of rotary controls. Detection thresholds for changes in friction and inertia were determined and found to be about 10 to 20 per cent of the initial values.

Effects of rotary inertia on the supersonic flutter of sandwich panels

AIAA Journal, 1971
A theoretical analysis is presented for the supersonic flutter of a simply-supported isotropic sandwich panel. The aerodynamic loading is described by a static approximation valid for a wide range of Mach number. Small deflection theory for sandwich plates which considers transverse shear deformations and rotary inertia in addition to bending is used ...

The Influence of Lumped Rotary Inertia in Flexible Multibody Dynamics∗

Mechanics of Structures and Machines, 1990
ABSTRACT A computational method for dynamic analysis of flexible multi-body mechanisms is presented that extends lumped mass models to account for the influence of lumped rotary inertia. In order to account for the effect of lumped rotary inertia, a diagonal mass matrix is evaluated and the equations of motion are derived for a general diagonal mass ...

Problems with Transverse Shear and Rotary Inertia in Structural Analysis

46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005
Presented here are accurate influences of transverse shear and rotary inertias on static and dynamic characteristics of isotropic and composite beams. An energy-consistent beam theory is derived by accounting for non-uniform out-of-plane shear warping of cross sections.
