Piecewise Nonlinear Dynamic Modeling for Gear Transmissions With Rotary Inertia and Backlash [PDF]
IEEE Access, 2019 Establishing an accurate dynamic model for gear transmission is challenging because of the complex dynamic mechanical behavior of the gear transmission, particularly under difficult working conditions such as heavy loads and frequent starts and stops ...

Small size and rotary inertia effects on the natural frequencies of carbon nanotubes
Curved and Layered Structures, 2018 In the present paper, rotary inertia and small size effects on the free vibration response of single-walled carbon nanotubes are examined. The equations in motion and associated boundary conditions are obtained by using Hamilton’s principle on the basis ...

On rotary inertia of microstuctured beams and variations thereof
Mechanics Research CommunicationsWe discuss the classic rotary inertia notion and extend it for microstructured beams introducing new microinertia parameters as an additional dynamic response to microstructure changes. Slender structures made of beam- or platelet-lattice metamaterials may exhibit not only large translations and rotations but also general deformations of inner ...

On the use of a roving body with rotary inertia to locate cracks in beams [PDF]
Journal of Sound and Vibration, 2018 Abstract Identifying cracks and damages in structures using measured vibrational characteristics has received considerable attention in the past few decades. The possibility of using frequency changes due to the application of a mass appended to the structure has also been considered.

Modal behaviour of rotor considering rotary inertia and shear effects
Perspectives in Science, 2016 SummaryThe effect of rotary inertia and shear effect becomes an important aspect for heavy rotors. The Euler–Bernoulli beam element is used for approximation in case of slender rotors and it is necessary for heavy rotors to consider rotary inertia and shear effect. These effects tend to change the mass and stiffness matrix of shaft element.

The Influence of Shear Energy and Rotary Inertia to Beam Elements Oscillation
Механика машин, механизмов и материалов, 2008 The influence of correction for shear and rotary inertia in the case of free oscillating physically-nonlinear beams is analysed in the paper. The solution obtained via energetic methods with the usage of "moment-curvature" diagram.
