Natural Frequencies of Rectangular Plate With- and Without-Rotary Inertia

Journal of The Institution of Engineers (India): Series C, 2016
A nine-node isoparametric plate element, in conjunction with first-order shear deformation theory, was used for free vibration analysis of rectangular plates. Both thick and thin plate problems were solved for various aspect ratios and boundary conditions.

Influence of shear, rotary inertia on the dynamic characteristics of flexible manipulators

1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999). Conference Proceedings (Cat. No.99CH36368), 2003
The influence of shear, rotary inertia on the dynamic characteristics of flexible manipulators is studied through frequency analysis. In terms of the various geometric effects, dynamic models of flexible manipulators are set up and characteristic equations are derived.

Effect of rotary inertia on vibration of tapered beams

International Journal for Numerical Methods in Engineering, 1986
AbstractRotary inertia and dynamic‐correction rotary inertia matrices for a linearly tapered beam element of any cross‐sectional shape are derived in explicit form. Exact expressions for the required displacement functions are used in the derivation of these matrices.

Mass and rotary inertia sensing from vibrating cantilever nanobeams

SPIE Proceedings, 2016
Nano-mechanical sensing exploiting frequency shift of a cantilever beam to obtain the mass of an object is well established. This paper is aimed at investigating the possibility of sensing mass as well as rotary inertia of an attached object. The rotary inertia of an object gives additional insight into its shape, which is a key motivation of this work.

The Active Rotary Inertia Driver for Vibration Control of Suspended Structures

2020
The traditional TMD and AMD are ineffective for the swing vibration control of suspended structures. Although the recently proposed tuned rotary inertia damper (TRID) is effective for swing vibration control, it has the limitations of low robustness and limited application range.

A piezoelectric inertia rotary actuator based on asymmetric clamping mechanism

Microsystem Technologies, 2015
A newly piezoelectric inertia rotary actuator is presented by using asymmetric mechanical structure to produce asymmetric inertia impact force when the symmetric electrical signal is applied to the piezoelectric bimorph Mechanical analysis was derived and simulation model of asymmetric clamping mechanism was established to determine the influence of ...

The Influence of shearing and rotary inertia on the resonant properties of gold nanowires

Journal of Applied Physics, 2010
In a previous publication [P. A. T. Olsson, J. Appl. Phys. 108, 034318 (2010)], molecular dynamics (MD) simulations have been performed to study the resonant properties of gold nanowires. It has been documented in the aforementioned publication that the eigenfrequencies of the fundamental mode follows the continuum mechanically predicted behavior when ...

Effect of shear deformations and rotary inertia on optimum beam frequencies

International Journal for Numerical Methods in Engineering, 1975
AbstractAccounting for shear deformations and rotary inertia effects, necessary condition for optimum fundamental frequency of a vibrating beam of constant volume and with a given distribution of non‐structural mass, is obtained through the calculus of variations.

Effect of rotary inertia and shear on natural frequencies of cantilever bridges

Journal of Sound and Vibration, 1975
A study of the natural frequencies of cantilever bridges including the effects of rotary inertia and shear deformation is presented. The bridge is assumed to act as a series of elastic beams with distributed mass. Frequency equations are derived for the symmetric and the antisymmetric vibrations.

Transverse Vibration of Beams with Internal Damping, Rotary Inertia, and Shear

The Journal of the Acoustical Society of America, 1963
The manner in which the Timoshenko equation may be extended to predict the response to vibration of beams with internal damping has been discussed in detail. The conventional form of the Timoshenko equation describes how the presence of rotary inertia and shear displacement influences the vibrational response of beams when the bending wavelength is not
